Mayelana nalolu hlelo lokusebenza

Nge lensiza ungathatha phansi kwendlu yakho, usethe indawo ye-WiFi router, futhi ulingise ukuthi amaza kagesi we-WiFi e-electromagnetic asabalalisa kanjani.

Bona uhlelo lokusebenza lusebenza kuvidiyo elandelayo ngewebhusayithi yezindaba yobuchwepheshe I-Verge:

Lolu hlelo lokusebenza lususelwa ekuthumeleni kwe-'Helmhurts 'kubhulogi lami elithi' Cishe Kubukeka Njengomsebenzi ', elifakwe kwi-Engadget, Ars Technica, nakwezinye izincwadi eziningi:

Lolu hlelo lokusebenza lusebenzisa indlela ye-2D Finite umehluko wesikhathi se-Domain (FDTD) ukuxazulula i-equation kaMaxwell kwigridi yeCarlesian. Isibonelo seplanethi efakwe kuhlelo lokusebenza.

Isetshenziswa kanjani:

Iplanethi yakho yephansi idinga ukuba yifayela le-.png, enendawo engenalutho emakwe mnyama futhi nezinto ezimakwe ngemibala. Izithombe zizoguqulwa zibe yimpahla efanelekile ekulayelweni - lokhu kungathatha imizuzwana embalwa.

Amaphikiseli akhiwe kumasentimitha angu-1, ngakho-ke silinganisa phansi ngokufanele.

Ukulingiswa kukhawulelwe ngejubane ngenxa yeprosesa leselula, ngakho-ke zama ukugcina izithombe ngezansi kwamaphikseli ayi-1000x1000

Thinta isithombe ukusetha indawo ye-router, emakwe umbuthano obomvu. Khetha amapharamitha we-antenna ngezansi.

Khetha ukuthi uzokwakha ini - 'Insimu' ingukuphakama kwensimu kagesi ngokushesha, i-'Flux 'yisilinganiso esilinganiswa nesikhathi sePoynting flux.

Chofoza ukuze uqalise bese ukuqalisa kuzoqala. Chofoza ukuma ukuze umise isikhashana nganoma yisiphi isikhathi - lokhu kusindisa inqubekela phambili yokulingisa engaqhubeka ngokuchofoza uqhubeke futhi. Ukuze usethe kabusha, vula isithombe futhi.

Ukuze ulondoloze umphumela wokulingisa njengesithombe, chofoza u-Gcina nganoma yisiphi isikhathi. Izithombe zigcinwa kwisitoreji sangaphakathi / sangaphandle futhi zengezwe ekugcineni komugqa wekhamera.

Ukuze uqale ukurekhoda ukumbumbuluzwa chofoza inkinobho yerekhodi 'R'. Lapho ukumbumbuluzwa kumiswa ukwenziwa kwe-GIF izithombe.

Ngaphansi kwe-bonnet:

I-antenna oscillates ku-2.4 GHz. Imiphetho yesithombe isebenzisa isimo esidonsayo semingcele njengakuMur 1981, IEEE Transaction on Electromagnetic Compatibility.

Lapho kuchazwa khona izindonga, ama-indices afanelekile we-Refractive indices kanye nokulahleka kwemisebe ye-2.4GHz kusetshenziswa.

Ukuzikhulula:

Lolu hlelo lokusebenza aluhloselwe ukufakwa esikhundleni samaphakeji esoftware wokulinganisa we-EM.
Njengokusondela kwe-2D kufaka phakathi izindonga ezilula kuphela kungenzeka kungalingisi ngokunembile iplanethi enikezwe.
