Electromagnetic wave absorbent material inoreva rudzi rwezvinhu zvinogona kutora kana kuderedza zvakanyanya simba remagetsi rinotambirwa pamusoro payo, nekudaro kuderedza kukanganiswa kwemafungu emagetsi.Mumashandisirwo einjiniya, pamusoro pekuda kunyura kwakanyanya kwemafungu emagetsi mune yakakura frequency bhendi, iyo inonwisa zvinhu inodiwa zvakare kuve nehuremu huremu, kupikisa tembiricha, humidity kuramba, uye corrosion resistance.

Nekuvandudzwa kwesainzi yemazuva ano uye tekinoroji, kukanganisa kwemagetsi emagetsi panharaunda kuri kuwedzera.Panhandare yendege, ndege haigone kusimuka nekuda kwekukanganiswa kwemagetsi emagetsi, uye inononoka;kuchipatara, mbozhanhare dzinowanzovhiringidza kushanda kwakajairika kweakasiyana emagetsi kuongororwa uye michina yekurapa.Naizvozvo, kurapwa kwekusvibiswa kwemagetsi uye kutsvaga chinhu chinogona kumira uye kunetesa electromagnetic wave radiation-absorbing zvinhu yave nyaya hombe muzvinhu zvesainzi.

Electromagnetic radiation inokonzera kukuvadza kwakananga uye kusiri kwakananga kumuviri wemunhu kuburikidza nekupisa, kusapisa, uye kuwedzera mhedzisiro.Zvidzidzo zvakasimbisa kuti ferrite inonwisa zvinhu zvine mashandiro epamusoro, ayo ane hunhu hwepamusoro absorption frequency bhendi, yakanyanya kunyura mwero, uye kutetepa kuenderana ukobvu.Kushandisa ichi chinhu kumidziyo yemagetsi kunogona kutora yakanyudza electromagnetic radiation uye kuzadzisa chinangwa chekubvisa kukanganiswa kwemagetsi.Zvinoenderana nemutemo wemafungu emagetsi ari kupararira pakati kubva pazasi magineti kusvika kune yakakwira magineti permeability, yakakwira magineti permeability ferrite inoshandiswa kutungamira mafungu emagetsi, kuburikidza neresonance, huwandu hukuru hwesimba rinopenya remagetsi emagetsi rinotorwa, uyezve simba re electromagnetic waves inoshandurwa kuita kupisa simba kuburikidza nekubatanidza.

Mukugadzirwa kwezvinhu zvinonwisa, nyaya mbiri dzinofanirwa kutariswa: 1) Kana iyo electromagnetic wave inosangana nepamusoro pechinhu chinotora, pfuura nepamusoro pepamusoro sezvinobvira kuderedza kufungisisa;2) Kana iyo electromagnetic wave ichipinda mukati meiyo inonwisa zvinhu, ita kuti iyo electromagnetic wave Irase simba zvakanyanya sezvinobvira.

Pazasi pane iripo Electromagnetic wave inonwisa zvinhu zvakabikwa mukambani yedu:

1).carbon-based absorbing materials, zvakadai se: graphene, graphite, carbon nanotubes;

2).iron-based absorbing materials, yakadai se: ferrite, magnetic iron nanomaterials;

3).ceramic inonwisa zvinhu, senge: silicon carbide.
