Idan ya zo ga yin caji a rayuwa, abin da kuka fara yi shine ko amfani da caja da kebul na caji.A cikin 'yan shekarun nan, adadin "caja mara waya" sun kasance a kasuwa, wanda za'a iya cajin "a cikin iska".Wadanne ka'idoji da fasaha ake amfani da su a cikin wannan?
Tun a shekarar 1899, masanin kimiyyar lissafi Nikola Tesla ya fara bincikensa na watsa wutar lantarki.Ya gina hasumiya mai watsa wutar lantarki mara waya a birnin New York, kuma ya yi tunanin hanyar watsa wutar lantarki mara waya: ta yin amfani da duniya a matsayin madugu na ciki da ionosphere na duniya a matsayin madubi na waje, ta hanyar haɓaka mai watsawa a cikin yanayin motsi na radial electromagnetic, wanda aka kafa tsakanin Duniya da ionosphere Yana sake fitowa a ƙananan mita na kusan 8Hz, sannan yana amfani da igiyoyin lantarki na saman da ke kewaye da duniya don watsa makamashi.
Ko da yake wannan ra'ayin ba a gane shi ba a lokacin, wani kwarin gwiwa ne na binciken caji mara waya da masana kimiyya suka yi shekaru dari da suka wuce.A halin yanzu, mutane sun ci gaba da yin bincike da gwadawa a kan haka, kuma sun sami nasarar haɓaka fasahar cajin mara waya.Ana aiwatar da manufar kimiyya ta asali sannu a hankali.
Cajin mara waya fasaha ce da ke amfani da hanyar tuntuɓar jiki ba don cimma nasarar watsa wutar lantarki ba.A halin yanzu, akwai fasahohin watsa wutar lantarki guda uku gama gari, wato electromagnetic induction, resonance electromagnetic, da kuma radiyo.Daga cikin su, nau'in induction na lantarki shine hanyar da ake amfani da ita sosai, wanda ba wai kawai yana da babban caji ba, amma kuma yana da ƙananan farashi.
Ka'idar aiki na fasahar caji mara igiyar waya ita ce: shigar da coil mai watsawa akan tashar caji mara waya, sannan shigar da na'urar karba a bayan wayar hannu.Lokacin da aka caje wayar hannu kusa da tushen caji, na'urar da ke watsawa za ta haifar da madadin filin maganadisu saboda an haɗa ta da madaidaicin halin yanzu.Canjin filin maganadisu zai haifar da wutar lantarki a cikin na'ura mai karɓa, don haka canja wurin makamashi daga ƙarshen watsawa zuwa ƙarshen karɓa, kuma a ƙarshe ya kammala aikin caji.
Canjin caji na hanyar caji mara waya ta shigar da wutar lantarki ya kai 80%.Domin magance wannan matsala, masana kimiyya sun fara wani sabon ƙoƙari.
A shekara ta 2007, wata tawagar bincike a Amurka ta yi nasarar amfani da fasahar resonance electromagnetic wajen kunna wutar lantarki mai karfin watt 60 da ke da nisan mita 2 daga tushen wutar lantarki, kuma ingancin watsa wutar ya kai kashi 40%, wanda ya fara gudanar da bincike da bunkasuwar ci gaban electromagnetic. resonance fasahar caji mara waya.
Ka'idar electromagnetic resonance fasahar caji mara igiyar waya iri daya ce da ka'idar resonance na sauti: na'urar watsa makamashi da na'urar karban makamashi ana daidaita su zuwa mitar guda daya, kuma ana iya musayar makamashin juna yayin resonance, ta yadda nada a cikin na'ura ɗaya na iya zama mai nisa.Nisa yana canja wurin wuta zuwa nada a wata na'ura, yana kammala cajin.
Fasahar caji mara igiyar waya ta na'urar lantarki tana karya iyakacin watsawa na induction induction na ɗan gajeren nesa, yana tsawaita nisan caji zuwa mita 3 zuwa 4 a matsakaicin, sannan kuma yana kawar da iyakokin cewa na'urar karba dole ne ta yi amfani da kayan ƙarfe yayin caji.
Domin kara yawan nisan watsa wutar lantarki mara waya, masu bincike sun kirkiro fasahar cajin igiyoyin rediyo.Ka'idar ita ce: na'urar watsawa ta microwave da na'urar karban microwave cikakken watsa wutar lantarki mara waya, ana iya shigar da na'urar watsawa a cikin bangon bango, kuma ana iya shigar da na'urar karba akan kowane samfurin mai ƙarancin wuta.
