ukucabanga okungalungile

Kukhona izibalo ezithuthuke kakhulu ngemuva kwakho konke—ososayensi badinga ukuzisebenzisa ukuze bathole indlela yokusetha amalensi amabili ukuze ukukhanya kuphindeke ngendlela yokuthi bakwazi ukufihla into ngemva kwawo. Lesi sixazululo asisebenzi kuphela uma ubheka ngqo kuma-lens - i-engeli ye-degrees engu-15 noma enye yanele. Ingasetshenziswa ezimotweni ukuze kuqedwe izindawo ezingaboni emehlweni ezibukweni noma emakamelweni okuhlinza, okuvumela odokotela abahlinzayo ukuba babone ngezandla zabo.

Lokhu ngolunye umjikelezo omude wezambulo mayelana nobuchwepheshe obungabonakali obufike kithi eminyakeni yamuva. Ngo-2012, sesivele sezwa nge-"Cap of Invisibility" evela e-American Duke University. Mayelana nokuthi bekumayelana nani ukungabonakali kwe-cylinder encane engxenyeni encane ye-microwave spectrum. Ngonyaka odlule, izikhulu zikaDuke zabika ngobuchwepheshe be-sonar stealth obungase bubonakale buthembisa kweminye imibuthano.

Ngeshwa, kwakumayelana nokungabonakali kuphela ngokombono othile futhi ngezinga elilinganiselwe, okwenza ubuchwepheshe bungasetshenziswa kancane. Ngo-2013, onjiniyela abangakhathali e-Duke bahlongoza idivayisi ephrintiwe ye-3D eyafihla into ebekwe ngaphakathi enezimbobo ezincane esakhiweni. Nokho, futhi, lokhu kwenzeka ebangeni elilinganiselwe lamagagasi futhi kuphela ngombono othile. Ezithombeni ezishicilelwe ku-inthanethi, ijazi lemvula lenkampani yaseCanada elinegama elithakazelisayo elithi Quantum Stealth lalibukeka lithembisa.

Ngeshwa, ama-prototypes asebenzayo awakaze aboniswe, futhi akukaze kuchazwe ukuthi kusebenza kanjani. Inkampani icaphuna izinkinga zokuphepha njengesizathu futhi ibika ngokufihlekile ukuthi ilungiselela amasosha izinguqulo eziyimfihlo zomkhiqizo. Sikumema ukuthi ufunde udaba kukhona kusitoki.
