Ihe dị iche n'etiti ihe na-egbochi RF na ihe na-ekesa RF

N'ọrụ bara uru, a na-akpọkarị ihe ndị na-egbochi RF na ihe ndị na-ekesa RF n'otu oge.
Kedu ihe dị iche n'etiti ihe ndị na-egbochi RF na ihe ndị na-agbasa RF?
Isiokwu a ga-elekwasị anya n'ịkọwa okwu ndị a.
Ihe na-egbochi redio frequency, nke a makwaara dị ka ngwaọrụ unidirectional, bụ ngwaọrụ nke na-ebufe ebili eletriki n'otu ụzọ. Mgbe ebili eletriki na-agbasa n'akụkụ ihu, ha nwere ike inye ike niile na ibu ahụ ma mee ka ebili mmiri ndị a na-egosipụta site na ibu ahụ belata nke ukwuu. Enwere ike iji njirimara nnyefe unidirectional a chọpụta mmetụta nke mgbanwe ibu na isi iyi mgbaàmà.
Ndị na-agbasa RF bụ sistemụ nnyefe alaka nwere njirimara na-abụghị nke otu. Ndị na-agbasa RF ferrite a na-ejikarị eme ihe bụ ndị na-agbasa RF nke dị ka Y, nke mejupụtara ahịrị alaka atọ nke kesara n'otu akụkụ nke 120 ° n'akụkụ ibe ha.

1,Kedu ihe bụ ihe na-eme ka ihe na-adịghị mma nke RF dị?
Ihe na-egbochi redio ugboro ugboro, nke a makwaara dị ka ngwaọrụ unidirectional, bụ ngwaọrụ nke na-ebufe ebili mmiri electromagnetic n'otu ụzọ. Mgbe ebili mmiri electromagnetic na-agbasa n'akụkụ ihu, ha nwere ike inye ike niile na ibu ahụ ma mee ka ebili mmiri ndị a na-egosipụta si na ibu ahụ belata nke ukwuu. Enwere ike iji njirimara nnyefe unidirectional a chọpụta mmetụta nke mgbanwe ibu na isi iyi mgbaàmà. Site n'iji ihe na-akpali field dị ka ihe atụ, kọwaakwuo ụkpụrụ ọrụ nke ihe na-egbochi ferrite RF.

A na-eme ihe ndị na-ekewapụ mgbanwe ubi dabere na mmetụta dị iche iche nke mgbanwe ubi nke ferrite na ụdị ebili mmiri na-ebuga n'akụkụ abụọ. Ọ na-agbakwụnye efere mbelata n'akụkụ mpempe akwụkwọ ferrite, n'ihi ọdịiche dị iche iche nke ubi ndị ntụziaka abụọ nke nnyefe mepụtara, oghere eletrik nke ebili mmiri na-ebuga na ntụziaka ihu (- z direction) na-agbagọ n'akụkụ na-enweghị efere mbelata, ebe oghere eletrik nke ebili mmiri na-ebuga na ntụziaka azụ (+ z direction) na-agbagọ n'akụkụ efere mbelata, si otú a na-enweta ọrụ nkewa nke obere mbelata n'ihu na nnukwu mbelata nlọghachi, dịka egosiri na Foto2.

2,Kedu ihe bụ ihe mgbasa ozi RF?
Ndị na-agbasa RF bụ sistemụ nnyefe alaka nwere njirimara na-abụghị nke otu. Ndị na-agbasa RF ferrite a na-ejikarị eme ihe bụ ndị na-ekesa RF dị ka Y, dịka egosiri na Foto 3 (a), nke mejupụtara ahịrị alaka atọ nke kesara n'otu akụkụ nke 120 ° n'akụkụ ibe ha. Mgbe ebe ndọta mpụga bụ efu, a naghị emepụta ferrite, yabụ magnetism n'akụkụ niile bụ otu. Mgbe e tinyere akara ngosi site na ahịrị alaka "①", ebe ndọta dịka egosiri na Foto 3 (b) ga-enwe mkpali na njikọ ferrite. N'ihi otu ọnọdụ maka alaka "②, ③", a na-emepụta akara ngosi ahụ n'akụkụ hà nhata. Mgbe etinyere ebe ndọta kwesịrị ekwesị, a na-eme ka ferrite bụrụ magnet, n'ihi mmetụta nke anisotropy, ebe ọkụ eletrik dịka egosiri na Foto 3 (c) na-akpali akpali na njikọ ferrite. Mgbe etinyere ferrite magnet kwesịrị ekwesị, a na-eme ka magnetik dị n'otu ụzọ, n'ihi mmetụta nke anisotropy, enwere mmepụta mgbaàmà na alaka "②", ebe ubi eletriki dị n'alaka "③" bụ efu ma enweghị mmepụta mgbaàmà. Mgbe ntinye sitere na alaka "②", alaka "③" nwere mmepụta, ebe alaka "①" enweghị mmepụta; Mgbe ntinye sitere na alaka "③", alaka "①" nwere mmepụta ebe alaka "②" enweghị mmepụta. A pụrụ ịhụ na ọ na-emepụta mgbasa ozi otu ụzọ nke "①" → "②" → "③" → "①", na ntụzịaka azụ ejikọtaghị, ya mere a na-akpọ ya mgbasa ozi RF.
