ʻO ka mea hoʻoheheʻe hawewe electromagnetic e pili ana i kahi ʻano mea hiki ke hoʻopaʻa a hōʻemi nui paha i ka ikehu hawewe electromagnetic i loaʻa ma luna o kona ʻili, a laila e hōʻemi ana i ka interference o nā hawewe electromagnetic.I loko o nā noi ʻenekinia, ma waho aʻe o ka koi ʻana i ka absorption kiʻekiʻe o nā hawewe electromagnetic i kahi alapine ākea, pono nō hoʻi ka mea hoʻoheheʻe e loaʻa ke kaumaha māmā, ke kūpaʻa wela, ka pale ʻana i ka haʻahaʻa, a me ke kūpaʻa corrosion.

Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana hou, ke piʻi nei ka hopena o ka radiation electromagnetic i ke kaiapuni.Ma ke kahua mokulele, ʻaʻole hiki ke lele ka lele ma muli o ke keakea ʻana o ka nalu electromagnetic, a ua lohi ia;ma ka halemai, hoʻopilikia pinepine nā kelepona paʻa i ka hana maʻamau o nā ʻano ʻike uila like ʻole a me nā lako lapaʻau.No laila, ʻo ka mālama ʻana i ka pollution electromagnetic a me ka ʻimi ʻana i kahi mea hiki ke kū a hoʻonāwaliwali i ka hawewe electromagnetic radiation-absorbing material i lilo i mea nui i ka ʻepekema waiwai.

Hoʻopilikia ka electromagnetic radiation i ke kino kanaka ma o ka wela, non-thermal, a me nā hopena kumulative.Ua hōʻoia ʻia nā haʻawina ʻoi aku ka maikaʻi o nā mea hoʻoheheʻe ferrite, nona nā hiʻohiʻona o ke kiʻekiʻe absorption frequency band, kiʻekiʻe absorption rate, a me ka mānoanoa like ʻole.ʻO ka hoʻopili ʻana i kēia mea i nā mea uila hiki ke hoʻopaʻa i ka radiation electromagnetic leaked a hoʻokō i ke kumu o ka hoʻopau ʻana i ka interference electromagnetic.Wahi a ke kānāwai o nā hawewe electromagnetic e hoʻolaha ana i ka waena mai ka haʻahaʻa haʻahaʻa a hiki i ke kiʻekiʻe magnetic permeability, hoʻohana ʻia ka ferrite magnetic permeability kiʻekiʻe e alakaʻi i nā hawewe electromagnetic, ma o ka resonance, ka nui o ka ikehu uila o nā hawewe electromagnetic, a laila ka ikehu o hoʻololi ʻia nā hawewe electromagnetic i ikehu wela ma o ka hoʻohui ʻana.

I ka hoʻolālā ʻana o ka mea hoʻoheheʻe ʻia, pono e noʻonoʻo ʻia ʻelua mau pilikia: 1) Ke hālāwai ka nalu electromagnetic i ka ʻili o ka mea hoʻoheheʻe, e hele i ka ʻili e like me ka hiki ke hōʻemi i ka noʻonoʻo;2) Ke komo ka nalu electromagnetic i loko o ka mea hoʻomoe, e hana i ka hawewe electromagnetic E lilo ka ikehu e like me ka hiki.

Aia ma lalo iho nei ka hawewe electromagnetic i loaʻa i nā mea maka i kā mākou hui:

1).ʻO nā mea hoʻoheheʻe kalapona, e like me: graphene, graphite, carbon nanotubes;

2).nā mea hoʻopaʻa i ka hao, e like me: ferrite, magnetic iron nanomaterials;

3).nā mea hoʻoheheʻe ceramic, e like me: silicon carbide.
