ʻO nā alapine lekiō kahi ʻano o ka ikehu electromagnetic hiki ke hoʻohana ʻia no ke kamaʻilio, ka hāʻawi ʻana i ka mana, a me nā noi ʻē aʻe. Mai ka 20 kHz a i ka 300 GHz ka palena o luna, ʻo ia nā alapine leo a ʻo ka palena haʻahaʻa ʻo ia nā alapine infrared. Hoʻohana ʻia kēia mau alapine no ka hoʻokumu ʻana i nā au uila oscillating e ʻā ana ma ka lewa e like me nā hawewe lekiō.
Hiki i nā kumu like ʻole ke kuhikuhi i nā palena o luna a me lalo no ka laulā alapine. ʻO nā au uila e oscillate i nā alapine lekiō he mau waiwai kūikawā ʻaʻole i hoʻokaʻawale ʻia e ke au pololei a i ʻole ke alapine leo haʻahaʻa. No ka laʻana, hiki i nā au RF ke komo hohonu i loko o nā conductors uila a makemake e kahe ma luna o nā ʻili, i ʻike ʻia ʻo ka hopena ʻili. Ke hoʻopili ʻia nā au RF i ke kino, hiki iā lākou ke hoʻoulu i kahi ʻeha ʻeha a me ka ʻokiʻoki ʻana o ka ʻiʻo, a me ka haʻalulu uila.
Hiki i nā ʻōhua haʻahaʻa haʻahaʻa ke hoʻopuka i kēia mau hopena, akā ʻaʻole i hōʻeha ʻia nā kahawai RF a ʻaʻole e hōʻeha ʻia i loko a i ʻole ke ahi maʻamau, i kapa ʻia ʻo RF burns. Hiki i nā kahawai RF ke hiki ke maʻalahi i ka ea, e hana i kahi ala conductive. Hoʻohana ʻia kēia waiwai i nā ʻāpana alapine kiʻekiʻe no ka wiliwili arc uila. Hiki ke hoʻohana ʻia nā au RF no ka hāʻawi ʻana i ka mana, no ka mea hiki iā lākou ke ʻike e kahe ma nā ala i loaʻa nā mea insulating, e like me ka insulator dielectric a i ʻole ka capacitor.
ʻIke ʻia kēia ma ke ʻano he capacitive reactance, a ke emi nei ia i ka piʻi ʻana o ke alapine. ʻO ka hoʻohālikelike ʻana, ua ālai ʻia nā au RF e kahi wili o ka uea a i ʻole ka huli hoʻokahi o kahi uea piko, i ʻike ʻia ʻo ka inductive reactance. Piʻi kēia i ka piʻi ʻana o ke alapine. Hoʻohana pinepine ʻia nā au RF ma o nā kaula uila maʻamau, akā loaʻa iā lākou ka manaʻo e noʻonoʻo i ka pau ʻole o ke kaula, e like me nā mea hoʻohui. Hiki i kēia ke ho'iho'i i ke au i ke kumu, e hana ai i kahi kūlana i kapa 'ia he nalu kū. Hiki ke lawe maikaʻi ʻia nā au RF ma o nā laina hoʻouna a me nā kaula coaxial.
Ua māhele ʻia ka lekiō i nā pūʻulu, a ua hāʻawi ʻia kēia mau inoa maʻamau e ka International Telecommunication Union (ITU). Hoʻohana ʻia nā alapine lekiō i nā ʻano mea like ʻole o kēlā me kēia lā, e like me nā mea hoʻolele, nā mea hoʻokipa, kamepiula, televise, a me nā kelepona paʻa. Hoʻohana ʻia lākou i nā ʻōnaehana o kēia manawa, me ke kelepona a me nā kaʻa kaʻa kaʻa, a me ka ʻenehana kaapuni ʻo Mos. ʻO ka hoʻonui ʻia ʻana o nā mea kelepona uila uila, e like me nā kelepona, ua alakaʻi i nā noi lapaʻau no ka ikehu lekiō, me ka diathermy a me ka hyperthermy lapaʻau no ka maʻi kanesa, nā scalpels electrosurgery e ʻoki a hoʻopaʻa i nā hana, a me ka radiofrequency ablation.
Hoʻohana pū ʻia ke kiʻi ʻoniʻoni magnetic (MRI) i nā hawewe lekiō e hana i nā kiʻi o ke kino kanaka. ʻO nā mea ho'āʻo no nā alapine lekiō me nā mea hana maʻamau no ka hopena haʻahaʻa o ka laulā, a me nā mea hana hoʻokolohua kūikawā no nā alapine kiʻekiʻe. I ka hana ʻana me RF, pono maʻamau nā mea hana kūikawā, a ʻo ka RF maʻamau e pili ana i nā oscillations uila. ʻAʻole maʻamau nā ʻōnaehana RF mechanical, akā aia nā mechanical Ho'oponopono a me RF MEMS.

Ke kuleana o nā lekiō ma ka ʻoihana: Telephony, Control Circuits, MRI
ʻO nā alapine lekiō (RF) ke hoʻololi nei i nā au uila a i ʻole nā voltage e hana i kahi kahua electromagnetic. Hoʻohana ʻia lākou i nā ʻano noi like ʻole, mai nā mea i kēlā me kēia lā e like me ke kīwī a me nā kelepona paʻalima, i nā hoʻohana kūikawā hou aku e like me ka uila arc a me ka hāʻawi ʻana i ka mana. Loaʻa i nā alapine RF ka laulā o 20 kHz a i 300 GHz, me ka hopena haʻahaʻa o ka laulā he mau leo leo a ʻo ka hope luna he mau alapine infrared. Loaʻa i nā au RF nā waiwai kūikawā e pono ai lākou i ka ʻoihana. No ka laʻana, hiki iā lākou ke komo hohonu i loko o nā conductors uila, e ʻae iā lākou e hoʻohana ʻia i ke kelepona a me nā kaʻa kaʻa. Hiki ke hoʻohana ʻia i nā noi lapaʻau e like me MRI, e hoʻohana ana i nā hawewe lekiō e hana i nā kiʻi o ke kino kanaka.
Hiki ke hoʻohana ʻia nā au RF i nā mea hoʻāʻo no nā alapine kiʻekiʻe, a i nā ʻōnaehana o kēia manawa no ka ʻenehana kaapuni hoʻohui a me ke kelepona uila. Eia nō naʻe, paʻakikī ka hana ʻana me nā alapine RF. No ka laʻana, ʻike ʻia nā kahawai RF i nā mea ʻole i nā kaula a me nā mea hoʻohui, e hana ana i kahi kūlana i kapa ʻia he nalu kū. Loaʻa iā lākou ka waiwai o ka hiki ke ʻike ʻia e kahe ma nā ala i loaʻa nā mea insulating, e like me kahi insulator dielectric a i ʻole capacitor.
Hoʻohana ʻia kēia waiwai i nā ʻāpana alapine kiʻekiʻe no ka wiliwili arc uila. Eia kekahi, ke hoʻopili ʻia nā au RF i ke kino, hiki iā lākou ke hōʻeha i ka ʻeha ʻeha a me ka ʻokiʻoki ʻana o ka ʻiʻo, a me ka haʻalulu uila. Hiki i nā au ala haʻahaʻa ke hana i ka ʻeha o loko a me ke ahi maʻamau, i kapa ʻia ʻo RF burns. Loaʻa i nā alapine RF ka nui o ka hoʻohana ʻana i ka ʻoihana, mai ke kelepona a me nā kaʻa kaʻa a hiki i ka MRI a me ka ʻenehana kaapuni i hoʻohui ʻia. ʻOiai hiki iā lākou ke pōmaikaʻi, hiki iā lākou ke pōʻino, a pono e mālama pono i ka wā e hana pū ai me lākou. Me ka hoʻonui ʻia ʻana o nā mea kelepona uila uila uila, e like me nā kelepona, he mea nui ia e hoʻomaopopo i nā pilikia a me nā pono o nā alapine RF.
Ka hopena o nā lekiō i ke ola kino: ʻeha uila, ʻeha, ʻoki uila, hoʻopau i ka radiofrequency.
ʻO nā alapine lekiō (RF) he mau nalu electromagnetic i hoʻohana ʻia no nā noi like ʻole, mai ke kamaʻilio ʻana a hiki i nā lāʻau lapaʻau. Hoʻokaʻawale ʻia lākou i ʻekolu mau ʻāpana: kHz, GHz, a me RF. Loaʻa i kēlā me kēia ʻano alapine kona mau waiwai ponoʻī a me nā hoʻohana, a me nā hopena olakino. Hoʻohana ʻia nā alapine KHz no nā noi leo, e like me ka lekiō a me ke kīwī. Hoʻohana ʻia lākou no ka hāʻawi ʻana i ka mana, no ka mea hiki iā lākou ke komo i nā conductors uila. Hoʻohana ʻia nā alapine GHz no ke kelepona uila, e like me ke kelepona a me nā kamepiula.
Hoʻohana ʻia lākou no nā lāʻau lapaʻau, e like me ka magnetic resonance imaging (MRI). Hoʻohana ʻia nā alapine RF no ka welding arc uila a me ka radiofrequency ablation, kahi lāʻau lapaʻau i hoʻohana ʻia e mālama i ka maʻi kanesa. Hiki i ka hoʻohana ʻana i nā alapine RF ke loaʻa nā hopena maikaʻi a maikaʻi ʻole i ke olakino. No ka laʻana, hiki i nā au alapine haʻahaʻa ke hoʻoulu i ka haʻalulu uila a me nā ʻeha ʻeha, ʻoiai ʻo ke au alapine kiʻekiʻe e hiki ke hoʻoulu i ke ahi superficial i kapa ʻia ʻo RF burns. Eia kekahi, hiki i nā au RF ke hoʻokaʻawale i ka lewa, e hana ana i kahi ala conductive e hiki ke hoʻohana ʻia no ka wili uila uila.
Eia nō naʻe, hiki i kēia waiwai like ke alakaʻi i ka pollution hawewe lekiō. ʻO ka hope, hoʻohana ʻia nā alapine RF i ka pūʻali koa no ka lekiō lekiō a me nā kuhikuhi pinepine. Hoʻohana ʻia lākou i ka ʻoihana no ke kelepona, nā kaʻa kaʻa, a me MRI. Eia kekahi, hoʻohana ʻia lākou e hoʻololi i ke kukui lekiō a me nā hawewe kani i ka lōʻihi a me ke alapine. ʻO ka holoʻokoʻa, loaʻa i nā alapine RF kahi ākea o ka hoʻohana ʻana, mai ka kamaʻilio ʻana i nā lāʻau lapaʻau. Hiki iā lākou ke loaʻa nā hopena maikaʻi a maikaʻi ʻole i ke olakino, ma muli o ke alapine a me ka noi. Ke hoʻomau nei ka ʻenehana, ʻoi aku ka nui o ka hoʻohana ʻana i nā alapine RF.
