Y\u00fczy\u0131llar boyunca g\u00f6r\u00fcnmezlik fikri insan hayal g\u00fcc\u00fcn\u00fc b\u00fcy\u00fclemi\u015f, say\u0131s\u0131z casus, s\u00fcper kahraman ve b\u00fcy\u00fcl\u00fc yarat\u0131k hikayesine ilham vermi\u015ftir. Ger\u00e7ek g\u00f6r\u00fcnmezlik pelerinleri hala uzak bir hayal olsa da bilim insanlar\u0131 nesneleri insan g\u00f6z\u00fc i\u00e7in g\u00f6r\u00fcnmez k\u0131labilecek malzemeler ve cihazlar geli\u015ftirmede \u00f6nemli ilerlemeler kaydettiler.<\/p>\n\n

I\u015f\u0131k bir nesneye \u00e7arpt\u0131\u011f\u0131nda, \u0131\u015f\u0131\u011f\u0131n bir k\u0131sm\u0131 emilir, bir k\u0131sm\u0131 yans\u0131r ve bir k\u0131sm\u0131 nesneden ge\u00e7er. Bir malzemenin k\u0131r\u0131lma indisi, \u0131\u015f\u0131\u011f\u0131n i\u00e7inden ge\u00e7erken ne kadar b\u00fck\u00fcld\u00fc\u011f\u00fcn\u00fc belirler. Bir nesnenin k\u0131r\u0131lma indisini \u00e7evresiyle e\u015fle\u015ftirerek nesnenin g\u00f6r\u00fcnmez g\u00f6r\u00fcnmesini sa\u011flamak m\u00fcmk\u00fcnd\u00fcr.<\/p>\n\n

Metamalzemeler ve D\u00f6n\u00fc\u015f\u00fcm Opti\u011fi<\/h3>\n\n

Son y\u0131llarda ara\u015ft\u0131rmac\u0131lar, \u0131\u015f\u0131\u011f\u0131 benzeri g\u00f6r\u00fclmemi\u015f \u015fekillerde manip\u00fcle edebilen metamalzemeler ve d\u00f6n\u00fc\u015f\u00fcm opti\u011fi olarak bilinen geli\u015fmi\u015f malzemeler geli\u015ftirdiler. Bu malzemeler \u0131\u015f\u0131\u011f\u0131 b\u00fckebilir, odaklayabilir ve hatta iptal edebilir ve nesneleri g\u00f6r\u00fcnmez k\u0131labilen cihazlar\u0131n olu\u015fturulmas\u0131n\u0131 sa\u011flar.<\/p>\n\n

Y\u00fcksek teknolojili g\u00f6r\u00fcnmezlik pelerinleri hala geli\u015ftirilme a\u015famas\u0131nda olsa da k\u00fc\u00e7\u00fck nesneleri evde g\u00f6r\u00fcnmez k\u0131lman\u0131n basit ve ucuz bir yolu vard\u0131r. At-Bristol Bilim Merkezi’nde Ross Exton taraf\u0131ndan g\u00f6sterilen bu teknik, nesneyi k\u0131r\u0131lma indisi nesnenin k\u0131r\u0131lma indisine e\u015fit olan bir s\u0131v\u0131ya bat\u0131rmay\u0131 i\u00e7erir.<\/p>\n\n
