He mahi nui tā te taura raraunga hei tuku tohu raraunga. Engari ina whakamahia tonutia, tera pea he momo mōhiohio pokanoa katoa. Me whakaaro tātou mēnā ka uru ēnei tohu pokanoa ki te ara iahiko o roto o te taura raraunga, ā, ka taupatupatu ki te tohu i tukuna tuatahitia, ka taea rānei te pokanoa, te whakarerekē rānei i te tohu i tukuna tuatahitia, ā, ka ngaro ngā tohu whai hua, ngā raruraru rānei?

Ka tiakina, ka tiakina hoki ngā mōhiohio kua tukuna e te paparanga whiri me te paparanga pepa konumohe. Ehara i te mea he paparanga tiaki e rua ngā taura raraunga katoa, ko ētahi he paparanga tiaki maha, ko ētahi kotahi anake, kāore rānei he paparanga tiaki. Ko te paparanga tiaki he wehenga whakarewa i waenga i ngā rohe ā-wāhi e rua hei whakahaere i te whakaoho me te irahiko o ngā ngaru hiko, aukume me te aukume hikohiko mai i tētahi rohe ki tētahi atu.
Ina koa, hei karapoti i ngā matua o ngā ara iahiko ki ngā whakangungu rakau hei ārai i a rātou kei pāngia e ngā papa hikohiko/tohu wawaotanga o waho, ā, i te wa ano ka ārai i te horapa atu o ngā papa hikohiko/tohu wawaotanga i roto i ngā waea.
Ko te tikanga whānui, ko ngā taura e kōrerohia ana e tātou ko ngā momo waea matua whakamahana e whā, ngā taura takirua miro, ngā taura ārai me ngā taura honohono. He rerekē ngā rauemi e whakamahia ana e ēnei momo taura e whā, ā, he rerekē hoki ā rātou huarahi ki te ātete i te pokanoa hikohiko.
Ko te hanganga takirua miro te momo hanganga taura e whakamahia whānuitia ana. He māmā noa iho tōna hanganga, engari he kaha ki te whakakore i te pokanoa hikohiko. I te nuinga o te wā, ko te teitei ake o te nekehanga miro o ōna waea miro, ko te pai ake o te pānga tiaki. Ko te mahi a te rauemi o roto o te taura tiaki he kawe, he kawe aukume rānei, kia hanga ai he kupenga tiaki me te whakatutuki i te pānga ārai-aukume pai rawa atu. He paparanga tiaki whakarewa kei roto i te taura coaxial, ko te nuinga o te take nā tōna āhua o roto kua whakakiia ki te rauemi, ehara i te mea he pai anake ki te tuku tohu, ā, he tino whakapai ake i te pānga tiaki. I tēnei rā ka kōrero tātou mō ngā momo me ngā whakamahinga o ngā rauemi tiaki taura.
Rīpene Mylar pepa konumohe: He mea hanga te rīpene Mylar pepa konumohe ki te pepa konumohe hei rauemi turanga, te kiriata polyester hei rauemi whakapakari, ka herea ki te kāpia polyurethane, ka whakamarokehia i te pāmahana teitei, kātahi ka tapahia. Ko te rīpene Mylar pepa konumohe te nuinga o te wā e whakamahia ana i roto i te mata tiaki o ngā taura whakawhitiwhiti kōrero. Kei roto i te rīpene Mylar pepa konumohe ko te pepa konumohe taha-kotahi, te pepa konumohe taha-rua, te pepa konumohe whai parirau, te pepa konumohe rewa-wera, te rīpene pepa konumohe, me te rīpene hiato konumohe-kirihou; ka whakaratohia e te paparanga konumohe he kawe hiko pai rawa atu, he tiaki me te ārai-waikura, ka taea te urutau ki ngā momo whakaritenga.
Pepa konumohe Rīpene Mylar
Konumohe pepa whakarewa Ko te rīpene Mylar te mea nui hei ārai i ngā ngaru hiko auau-tiketike kia kore ai e pā ngā ngaru hiko auau-tiketike ki ngā kaiārahi o te taura, kia puta ai te iahiko whakaputa me te whakanui ake i te whakawhitiwhiti kōrero. Ina pā te ngaru hiko auau-tiketike ki te pepa whakarewa, e ai ki te ture a Faraday mō te whakaputa hiko, ka piri te ngaru hiko ki te mata o te pepa whakarewa, ka puta ai he iahiko whakaputa. I tēnei wā, me whai kaiārahi hei ārahi i te iahiko whakaputa ki roto i te whenua kia kore ai e pokanoa te iahiko whakaputa ki te tohu tuku.
He paparanga whiri (whakamaroke) pērā i ngā waea koranu parahi/konumohe-konupora. Ka hangaia te paparanga whakamaroke mā te whakamahi i ngā waea whakarewa me tētahi hanganga whiri mā roto i ngā taputapu whiri. Ko ngā rauemi o te whakamaroke ko ngā waea parahi (waea parahi tine), ngā waea koranu konumohe, ngā waea konumohe whakakikoruatia ki te parahi, te rīpene parahi (rīpene maitai pania kirihou), te rīpene konumohe (rīpene konumohe pania kirihou), te rīpene maitai me ētahi atu rauemi.
Rīpene Parahi
E rite ana ki te whiri whakarewa, he rerekē te mahi tiaki o ngā tawhā hanganga rerekē, ko te whai huatanga tiaki o te paparanga whiri ehara i te mea ko te kawe hiko, te urunga aukume me ētahi atu tawhā hanganga o te rauemi whakarewa anake e pā ana. Ā, ki te maha atu ngā paparanga, ka nui ake te hipoki, ka iti ake te koki whiri, ā, ka pai ake te mahi tiaki o te paparanga whiri. Me whakahaere te koki whiri i waenga i te 30-45°.
Mō te whiri paparanga kotahi, ko te reiti hipoki he pai ake i runga ake i te 80%, kia taea ai te huri ki ētahi atu momo pūngao pēnei i te pūngao wera, te pūngao pūmanawa me ētahi atu momo pūngao mā te ngaronga hysteresis, te ngaronga dielectric, te ngaronga ātete, me ētahi atu, me te whakapau i te pūngao kore e hiahiatia hei whakatutuki i te pānga o te tiaki me te mimiti i ngā ngaru hikohiko.
