Kūkākūkā ʻo Giovanni D'Amore i ka hoʻohana ʻana i nā mea hoʻoponopono impedance a me nā mea hana ʻoihana e ʻike ai i nā mea dielectric a me nā mea magnetic.
Ua maʻa mākou i ka noʻonoʻo e pili ana i ka holomua ʻenehana mai nā hanauna hoʻohālike kelepona paʻa a i ʻole nā ​​nodes kaʻina hana semiconductor. Hāʻawi kēia i nā holomua pōkole maikaʻi akā pohihihi i nā ʻenehana hiki (e like me ke kahua o ka ʻepekema waiwai).
ʻO ka mea nāna i hoʻokaʻawale i kahi TV CRT a i ʻole i hoʻā i kahi lako mana kahiko e ʻike i kahi mea: ʻAʻole hiki iā ʻoe ke hoʻohana i nā ʻāpana o ke kenekulia 20 e hana i nā mea uila 21st century.
No ka laʻana, ua hana ka holomua wikiwiki i ka ʻepekema waiwai a me ka nanotechnology i nā mea hou me nā hiʻohiʻona e pono ai ke kūkulu i nā inductors kiʻekiʻe, kiʻekiʻe-hana a me nā capacitors.
ʻO ka hoʻomohala ʻana i nā mea hana e hoʻohana ana i kēia mau mea pono ke ana pololei ʻana i nā waiwai uila a me nā mea magnetic, e like me ka permittivity a me ka permeability, ma luna o kahi ʻano o nā alapine hana a me nā pae wela.
ʻO nā mea dielectric ka mea nui i nā mea uila e like me nā capacitors a me nā insulators. Hiki ke hoʻoponopono ʻia ka dielectric mau o kahi mea ma o ka hoʻomalu ʻana i kona haku mele ʻana a / a i ʻole microstructure, ʻoi aku ka keramika.
He mea nui e ana i ka waiwai dielectric o nā mea hou i ka hoʻomaka ʻana o ka pōʻai hoʻomohala ʻāpana e wānana i kā lākou hana.
Hōʻike ʻia nā waiwai uila o nā mea dielectric e ko lākou permittivity paʻakikī, aia nā ʻāpana maoli a noʻonoʻo.
ʻO ka ʻāpana maoli o ka dielectric mau, i kapa ʻia ʻo ka dielectric mau, e hōʻike ana i ka hiki o kahi mea ke mālama i ka ikehu ke kau ʻia i kahi kahua uila. , ka mea e pono ai no nā capacitors kiʻekiʻe.
Hiki ke hoʻohana ʻia nā mea me nā dielectric mau haʻahaʻa e like me nā insulators pono i nā ʻōnaehana hoʻoili hōʻailona, ​​​​no ka mea ʻaʻole hiki iā lākou ke mālama i ka nui o ka ikehu, a laila e hōʻemi i ka lohi hoʻolaha hōʻailona ma o nā uea i hoʻopaʻa ʻia e lākou.
ʻO ka ʻāpana noʻonoʻo o ka permittivity paʻakikī e hōʻike ana i ka ikehu i hoʻopau ʻia e ka mea dielectric i loko o ke kahua uila.
Aia nā ʻano hana like ʻole o ke ana ʻana i ka dielectric mau. ʻO ke ʻano pāʻani like ʻole e waiho i ka mea ma lalo o ka hoʻāʻo ʻana (MUT) ma waena o nā electrodes ʻelua. Hoʻohana ʻia ka hoʻohālikelike i hōʻike ʻia ma ka Figure 1 e ana i ka impedance o ka mea a hoʻololi iā ia i kahi permittivity paʻakikī, ka mea. pili i ka mānoanoa o ka mea a me ka wahi a me ke anawaena o ka electrode.
Hoʻohana nui ʻia kēia ʻano no ke ana ʻana i ke alapine haʻahaʻa. ʻOiai he maʻalahi ke kumu, paʻakikī ke ana pololei ma muli o nā hewa o ke ana ʻana, ʻoi aku hoʻi no nā mea haʻahaʻa haʻahaʻa.
ʻOkoʻa ka permittivity paʻakikī me ke alapine, no laila pono e loiloi ʻia ma ke alapine hana.
ʻO ka dielectric material test fixture (e like me Keysight 16451B) he ʻekolu mau electrodes. ʻElua o lākou e hana i kahi capacitor, a ʻo ke kolu e hāʻawi i kahi electrode pale. Pono ka electrode pale no ka mea i ka wā i hoʻokumu ʻia ai kahi kahua uila ma waena o nā electrodes ʻelua, ʻāpana o ka electrode. e kahe ana ke kahua uila ma ka MUT i hoʻokomo ʻia ma waena o lākou (e nānā i ke Kiʻi 2).
ʻO ka noho ʻana o kēia kahua fringe hiki ke alakaʻi i ke ana hewa ʻana o ka dielectric mau o ka MUT. ʻO ka electrode pale e hoʻopaʻa i ke kahe e kahe ana ma ke kahua fringe, a laila e hoʻomaikaʻi ai i ke ana pololei.
Inā makemake ʻoe e ana i nā waiwai dielectric o kahi mea, he mea nui e ana wale ʻoe i ka mea a ʻaʻohe mea ʻē aʻe. electrode.
ʻElua mau ala e hoʻokō ai i kēia. ʻO ka mea mua e hoʻopili i nā electrodes kiʻi lahilahi i ka ʻili o ka mea e hoʻāʻo ʻia. ʻO ka lua ka loaʻa ʻana o ka permittivity paʻakikī ma ka hoʻohālikelike ʻana i ka capacitance ma waena o nā electrodes, i ana ʻia i ke alo a me ka ʻole. o na mea waiwai.
Hiki i ka electrode kiaʻi ke hoʻomaikaʻi i ka pololei o ke ana ʻana i nā alapine haʻahaʻa, akā hiki ke hoʻopilikia i ke kahua electromagnetic ma nā alapine kiʻekiʻe. Hāʻawi kekahi mau mea hōʻike i nā mea pono dielectric koho me nā electrodes paʻa e hiki ke hoʻonui i ka laulā pono o kēia ʻano ana. kōkua i ka hoʻopau ʻana i nā hopena o ka capacitance fringing.
Hiki ke hōʻemi ʻia nā hewa koena i hoʻokumu ʻia e nā fixtures a me nā mea hoʻopili e ka kaapuni ākea, pōkole pōkole a me ka hoʻouka ʻana.
ʻO ka loiloi i ke ʻano o ka hoʻololi ʻana o nā waiwai o nā mea dielectric me ka mahana e pono ai ka hoʻohana ʻana i nā keʻena wela a me nā kaula wela.
E like me nā mea dielectric, hoʻomaikaʻi mau ʻia nā mea ferrite, a hoʻohana nui ʻia i nā lako uila e like me nā ʻāpana inductance a me nā magnet, a me nā ʻāpana o nā transformers, nā mea hoʻoheheʻe magnetic a me nā suppressors.
ʻO nā hiʻohiʻona koʻikoʻi o kēia mau mea e pili ana i kā lākou permeability a me ka nalowale i nā alapine hana koʻikoʻi. ʻO kahi mea anana impedance me kahi mea hoʻopili magnetic hiki ke hāʻawi i nā ana kūpono a hiki ke hoʻihoʻi ʻia ma kahi ākea ākea.
E like me nā mea dielectric, ʻo ka permeability o nā mea magnetic he ʻano paʻakikī i hōʻike ʻia ma nā ʻāpana maoli a me ka noʻonoʻo. hoʻohana ʻia e hoʻemi i ka nui a me ke kaumaha o ka ʻōnaehana magnetic. Hiki ke hoʻemi ʻia ka ʻāpana poho o ka permeability magnetic no ka hana kiʻekiʻe loa i nā noi e like me nā transformers, a i ʻole i hoʻonui ʻia i nā noi e like me ka pale.
Hoʻoholo ʻia ka paʻakikī paʻakikī e ka impedance o ka inductor i hana ʻia e ka mea. no nā mea haʻahaʻa haʻahaʻa, he koʻikoʻi ke kihi o ka pae o ka impedance, ʻoiai ʻaʻole lawa ka pololei o ke ana ʻana.
Hoʻololi pū kekahi me ka wela, no laila e hiki i ka ʻōnaehana ana ke loiloi pololei i nā hiʻohiʻona wela ma kahi ākea ākea.
Hiki ke loaʻa ka paʻakikī paʻakikī ma ke ana ʻana i ka impedance o nā mea magnetic. Hana ʻia kēia ma ke kāʻei ʻana i kekahi mau uea a puni ka mea a me ke ana ʻana i ka impedance e pili ana i ka hopena o ke kaula. o ke kahua magnetic me kona kaiapuni a puni.
Hāʻawi ka mea hoʻāʻo mea magnetic (e nānā i ka Figure 3) i kahi inductor huli hoʻokahi e hoʻopuni ana i ka coil toroidal o ka MUT. .
Ke hoʻohana pū ʻia me ka impedance/material analyzer, hiki ke loiloi pololei ʻia ke ʻano maʻalahi o ka coaxial fixture a me ka toroidal MUT a hiki ke hoʻokō i kahi ākea ākea ākea mai 1kHz a 1GHz.
Hiki ke hoʻopau ʻia ka hewa i hana ʻia e ka ʻōnaehana ana ma mua o ke ana. ʻO ka hewa i hana ʻia e ka impedance analyzer hiki ke calibrated ma o ka hoʻoponopono hewa ʻekolu mau manawa. Ma nā alapine kiʻekiʻe, hiki i ka calibration capacitor haʻahaʻa haʻahaʻa ke hoʻomaikaʻi i ka pololei o ka huina.
Hiki i ka mea hoʻopili ke hāʻawi i kahi kumu hewa ʻē aʻe, akā hiki ke uku ʻia kekahi inductance koena ma ke ana ʻana i ka fixture me ka ʻole o ka MUT.
E like me ke ana dielectric, pono ke keʻena wela a me nā kaula pale wela e loiloi i nā ʻano wela o nā mea magnetic.
ʻOi aku ka maikaʻi o nā kelepona paʻalima, ʻoi aku ka holomua o nā ʻōnaehana kōkua hoʻokele a me nā kamepiula wikiwiki e hilinaʻi nei i ka holomua mau ʻana i nā ʻano ʻenehana. hoohana.
ʻO nā holomua hou loa o ka ʻepekema waiwai a me ka nanotechnology ua hiki ke hana i nā mea me nā waiwai dielectric a me ka magnetic ʻoi aku ka maikaʻi ma mua o ka wā ma mua. ua kau ʻia lākou.
Hiki i nā mea hana noʻonoʻo maikaʻi a me nā mea hana ke lanakila i ka nui o kēia mau pilikia a lawe mai i nā ana waiwai dielectric a me ka magnetic i nā mea hoʻohana i loaʻa ʻole ka ʻike kikoʻī i kēia mau kahua. ke kaiaola uila.
Ua hui pū ʻo "Electronic Weekly" me RS Grass Roots e kālele ana i ka hoʻolauna ʻana i nā ʻenekini uila ʻōpio maikaʻi loa ma UK i kēia lā.
E hoʻouna pololei i kā mākou nūhou, nā moʻomanaʻo a me nā manaʻo i kāu pahu leka!
