I nā ʻōnaehana lekiō a me nā ʻōnaehana microwave, ʻo ka hawewe ka hana kiʻekiʻe loa o ka interconnection a me nā ʻāpana passive, ka mea nui i ka band frequency i hāʻawi ʻia e hoʻouna maikaʻi i ka ikehu hōʻailona lekiō, a ʻo ke ʻano nui o ka hawewe he mau mea conductive metala, hiki ke mālama i nā pae mana kiʻekiʻe.
E like me ka inoa e hōʻike nei, pili pono nā ʻāpana hawewe pololei me ka hoʻololi ʻole ʻana i kāna kuhikuhi hoʻouna hōʻailona, a hiki ke hoʻololi ʻia ka lōʻihi e like me ke ʻano o ka noi, mai kahi mau kenimika a i kekahi mau mika.
Pono e noʻonoʻo ka hoʻolālā a me ka hana ʻana i nā ʻāpana pololei o ka hawewe nalu, e like me ke alapine hana, ka nui o ka nalu, ke koho ʻana i nā mea, ka ʻenehana hana, a me nā mea maʻamau.

Nā hiʻohiʻona:

1. Ma keʻano he laina hoʻouna, hana nā alakaʻi hawewe RF ma ka hoʻololiʻana i ka ikehu mai kekahi wahi ai kekahi, e loaʻa ana i ka hoʻouna maikaʻi ma o ka ho'ēmiʻana i ka poho ma ke kaʻina hana hoʻoili ikehu. Hiki i ka hollow metal structure o ka waveguide ke hoemi loa i ka poho ma ke kaʻina hoʻoili ikehu.
2. Ma ka like ole me ka antenna, aole e hooleleia ka ikehu i loko o ke ākea holoʻokoʻa i loko o ka hawewe nalu, akā ua nakinaki ia i loko o ka nalu, a me ka ikehu ma luna o ke alapine cutoff kiko'ī hiki ke hoʻouna 'ia ma o ka microwave waveguides.

Noi:

ʻAʻole i kaupalena ʻia nā noi o nā alakaʻi hawewe lekiō i nā kamaʻilio a me nā ʻōnaehana radar. No ka laʻana, i ka hyperlens kiʻi, hoʻohana ʻia nā papa kuhikuhi o nā alakaʻi hawewe pololei a me nā alakaʻi nalu curved e hoʻohālikelike i nā mea kuhikuhi pono a me ka maikaʻi ʻole no ka hoʻokō ʻana i ke kiʻi pilikino. He mea koʻikoʻi kēia ʻenehana i ka ʻenehana kiʻi kiʻi a me ka hoʻohui ʻana i nā photon, ʻoi loa i ka hoʻokō ʻana i ka hoʻoponopono pololei ʻana o ke kula māmā ma ka pālākiō hawewe lōʻihi.

Kaʻaleʻaleʻahoʻolako i nā ʻāpana pololei o ka nalu a hiki i ka 91.9GHz, a me nā sSsections pololei i hoʻonohonoho ʻia e like me nā koi o nā mea kūʻai aku. Welina mai nā mea kūʻai aku e nīnau hou aku i nā kikoʻī huahana.
