Electromagnetic Wave Absorbent Material

Ihe na-anabata ebili mmiri elektrọnik na-ezo aka n'ụdị ihe nwere ike ịmịnye ma ọ bụ belata nke ukwuu ike ikuku elektrọnịke a na-enweta n'elu ya, si otú a na-ebelata ndabichi nke ebili mmiri electromagnetic.N'ime ngwa injinia, gbakwunyere na-achọ nnabata dị elu nke ebili mmiri elektrọnik n'ọtụtụ ogologo oge, a na-achọkwa ihe na-amịkọrọ ahụ ka ọ nwee ịdị arọ dị arọ, nguzogide okpomọkụ, nguzogide iru mmiri na nguzogide corrosion.

Site na mmepe nke sayensị na teknụzụ ọgbara ọhụrụ, mmetụta nke radieshon electromagnetic na gburugburu ebe obibi na-abawanye.N'ọdụ ụgbọ elu, ụgbọ elu ahụ enweghị ike ịpụ n'ihi nnyonye anya ikuku electromagnetic, ọ na-egbukwa oge;N'ụlọ ọgwụ, ekwentị mkpanaaka na-egbochikarị ọrụ nkịtị nke ngwa elektrọnik dị iche iche na-achọpụta na ọgwụgwọ.Ya mere, ọgwụgwọ nke mmetọ electromagnetic na ịchọ ihe nwere ike iguzogide ma mee ka ike gwụ ihe ndị na-anata radieshon ebili mmiri aghọwo isi okwu na sayensị ihe.

Igwe ọkụ eletrik na-ebute mmerụ ahụ kpọmkwem na nke na-apụtaghị ìhè site na mmetụta ọkụ, nke na-abụghị nke ọkụ na mkpokọta.Nnyocha egosila na ihe ndị na-amịkọrọ ferrite na-arụ ọrụ kacha mma, nke nwere njiri mara ụda ugboro ugboro dị elu, ọnụego nnabata dị elu, na ọkpụrụkpụ dabara adaba.Itinye ihe a n'ime ngwa eletrọnịkị nwere ike ịmịnye radieshon eletrọnịkị ma nweta ebumnuche nke iwepụ nnyonye anya elektrọnik.Dị ka iwu nke electromagnetic ebili mmiri na-agbasa na ọkara si ala magnetik na elu magnetik permeability, akwa magnetik permeability ferrite na-eji na-eduzi electromagnetic ebili mmiri, site resonance, a nnukwu ego nke radiant ike nke electromagnetic ebili mmiri na-etinye obi gị dum, na mgbe ahụ ike nke. A na-atụgharị ebili mmiri electromagnetic ka ọ bụrụ ike ọkụ site na njikọta.

Na nhazi nke ihe na-adọrọ adọrọ, a ga-atụle okwu abụọ: 1) Mgbe ikuku electromagnetic na-ezute elu nke ihe na-adọrọ adọrọ, gafere n'elu dị ka o kwere mee iji belata ntụgharị uche;2) Mgbe ikuku electromagnetic na-abanye n'ime ime ihe na-adọrọ adọrọ, mee ka ikuku electromagnetic hapụ ike dị ka o kwere mee.

N'okpuru ebe a bụ ihe akụrụngwa na-amịpụta ihe eletrik dị na ụlọ ọrụ anyị:

1).ihe na-adọrọ adọrọ nke sitere na carbon, dị ka: graphene, graphite, carbon nanotubes;

2).ihe na-amịkọrọ ígwè, dị ka: ferrite, magnetik iron nanomaterials;

3).ihe na-adọrọ seramiiki, dị ka: silicon carbide.
