Aia kekahi makemakika maikaʻi loa ma hope o ia mea—pono nā kānaka ʻepekema e hoʻohana ia mea no ka ʻimi ʻana i ke ʻano o ka hoʻonohonoho ʻana i nā lens ʻelua i hoʻopaʻa ʻia ke kukui i hiki iā lākou ke hūnā pono i ka mea ma hope o lākou. ʻAʻole hana kēia hoʻonā i ka nānā pono ʻana i nā lens - kahi kihi o 15 degere a i ʻole ua lawa. Hiki ke hoʻohana ʻia i loko o nā kaʻa e hoʻopau i nā wahi makapō i nā aniani a i ʻole i loko o nā keʻena hana, e ʻae ana i nā kauka lapaʻau e ʻike i ko lākou mau lima.

ʻO kēia kekahi i loko o kahi pōʻai lōʻihi o nā hōʻike e pili ana i nā ʻenehana ʻike ʻole i hiki mai iā mākou i nā makahiki i hala. Ma 2012, ua lohe mua mākou e pili ana i ka "Cap of Invisibility" mai ke Kulanui ʻAmelika ʻAmelika. E pili ana i ka mea e pili ana ʻike ʻole ʻia o kahi puʻupuʻu liʻiliʻi ma kahi ʻāpana liʻiliʻi o ka spectrum microwave. I hoʻokahi makahiki ma mua, ua hōʻike nā luna o Duke i ka ʻenehana hoʻopunipuni sonar i manaʻo ʻia he mea hoʻohiki i kekahi mau pōʻai.

ʻO ka mea pōʻino, e pili ana i ka ʻike ʻole ʻia mai kahi ʻano o ka nānā ʻana a i kahi palena palena ʻole, ka mea i hoʻohana liʻiliʻi i ka ʻenehana. I ka makahiki 2013, ua hāʻawi ka poʻe ʻenekinia luhi ʻole ma Duke i kahi mea paʻi 3D e hoʻomoe i kahi mea i hoʻokomo ʻia i loko me nā micro-hole i loko o ka hale. Eia nō naʻe, ua hana ʻia kēia ma kahi palena o nā nalu a mai kahi ʻano wale nō. I loko o nā kiʻi i paʻi ʻia ma ka Pūnaewele, ʻike ʻia ka ʻaʻahu ua o ka hui Kanada me ka inoa hoihoi ʻo Quantum Stealth.

ʻO ka mea pōʻino, ʻaʻole i hōʻike ʻia nā prototypes hana, ʻaʻole i wehewehe ʻia pehea e hana ai. Hōʻike ka hui i nā pilikia palekana ke kumu a hōʻike cryptically e hoʻomākaukau ana i nā mana huna o ka huahana no ka pūʻali koa. Kāhea mākou iā ʻoe e heluhelu i ka pilikia loaʻa.
