Ko te pānga hiko-whatu e pā ana ki te pānga o te hurihanga o te taupū whakaata o tētahi rauemi ina pāngia he papa hiko. E rua ngā momo matua o te pānga hiko-whatu, ko tētahi ko te pānga hiko-whatu tuatahi, e mōhiotia ana ko te pānga Pokels, e pā ana ki te huringa rārangi o te taupū whakaata rauemi me te papa hiko e pāngia ana. Ko tētahi atu ko te pānga hiko-whatu tuarua, e mōhiotia ana ko te pānga Kerr, e rite ana te huringa o te taupū whakaata o te rauemi ki te tapawhā o te papa hiko. Ko te nuinga o ngā kaiwhakatikatika hiko-whatu e ahu mai ana i te pānga Pokels. Mā te whakamahi i te kaiwhakatikatika hiko-whatu, ka taea e tātou te whakarerekē i te āhua o te mārama e pā mai ana, ā, i runga i te whakarerekētanga āhua, mā tētahi huringa, ka taea hoki e tātou te whakarerekē i te kaha, te pōraritanga rānei o te mārama.
He maha ngā hanganga matarohia rerekē, e whakaaturia ana i te Pikitia 2. He hanganga whakarerekētanga kotahi katoa (a), (b) me (c) me te hanganga māmā, engari ko te whānui o te rārangi o te heru auau whatu i hangaia e herea ana e te whānui o te whānui hiko-whatu. Mena e hiahiatia ana he heru auau whatu me te auau auau teitei, e rua, neke atu rānei ngā whakarerekētanga e hiahiatia ana i roto i te cascade, e whakaaturia ana i te Pikitia 2(d)(e). Ko te momo hanganga whakamutunga e whakaputa ana i te heru auau whatu ka kiia he resonator hiko-whatu, koinei te whakarerekētanga hiko-whatu kua whakanohoia ki roto i te resonator, ka taea rānei e te resonator te whakaputa i te pānga hiko-whatu, e whakaaturia ana i te Pikitia 3.
PIK. 2 He maha ngā taputapu whakamātautau mō te whakaputa i ngā heru auau whatu i runga ingā kaiwhakatikatika hiko-whatu

03 Ngā āhuatanga o te heru auau whatu whakarerekētanga hiko-whatu
Painga tuatahi: te āheinga ki te whakarerekē
I te mea he pūmārama whānui-ātea te pūtake mārama, ā, he whānui auau mahi anō hoki tō te pūmārama hiko-whatu, ka taea hoki te whakarerekē auau i te heru auau whatu whakarerekētanga hiko-whatu. Haunga te auau whakarerekētanga, nā te mea ka taea te whakarerekē i te whakaputanga ngaru o te pūmārama, ka taea hoki te whakarerekē i te auau tāruarua o te heru auau whatu hua. He painga tēnei kāore i te whai i ngā heru auau whatu i hangaia e ngā taiaho aratau-raka me ngā moroiti-whakaoho.
Painga tuarua: te auau o te whakahokinga
Ehara i te mea he ngāwari noa te tere o te tāruarua, engari ka taea hoki te whakatutuki me te kore e whakarerekē i ngā taputapu whakamātautau. Ko te whānui o te rārangi o te heru auau whatu whakarerekētanga hiko-whatu he rite tonu ki te whānui o te whakarerekētanga, ko te whānui o te heru auau whatu whakarerekētanga hiko-whatu arumoni whānui he 40GHz, ā, ka taea e te auau tāruarua o te heru auau whatu whakarerekētanga hiko-whatu te nui ake i te whānui o te heru auau whatu i hangaia e ngā tikanga katoa engari ko te resonator moroiti (ka taea te eke ki te 100GHz).
Painga 3: te hanga āwhata
Ki te whakaritea ki te heru whatu i hangaia mā ētahi atu huarahi, ka whakatauhia te āhua o te kōpae whatu o te heru whatu whakarerekētanga hiko-whatu e te maha o ngā nekehanga herekore, pērā i te tohu auau reo irirangi, te ngaohiko pīrori, te porowhita taupatupatu, me ētahi atu, ka taea te whakamahi hei whakahaere i te kaha o ngā heru rerekē hei whakatutuki i te kaupapa o te hanga hihi.
04 Te whakamahinga o te heru auau whatu whakarerekētanga hiko-whatu
I roto i te whakamahinga mahi o te heru auau whatu whakarerekētanga hiko-whatu, ka taea te wehewehe ki ngā momo heru kotahi me ngā momo heru takirua. He tino whaiti te mokowā rārangi o te momo heru kotahi, nō reira ka taea te whakatutuki i te tika teitei. I taua wā anō, ki te whakatauritea ki te momo auau whatu i hangaia e te taiaho raka-aratau, he iti ake te taputapu o te momo auau whatu whakarerekētanga hiko-whatu, ā, he pai ake te whakarerekē. Ka hangaia te momo heru takirua mā te pokanoa o ngā momo heru takitahi e rua me ngā auau tāruarua rerekē, ā, ko te rerekētanga o te auau tāruarua ko te mokowā rārangi o te momo heru pokanoa hou. Ka taea te whakamahi i te hangarau momo auau whatu i roto i te whakaahua whatu, te whānuitanga, te ine matotoru, te whakatikatika taputapu, te hanga momo ngaru matapōkere, te whakaahua auau reo irirangi, te whakawhitiwhiti mamao, te huna whatu me ētahi atu.
PIK. 4 Te horopaki tono o te heru auau whatu: Mā te ine i te kōtaha matā tere-tiketike hei tauira
