Reflection is divided into specular reflection and diffuse reflection. Specular reflection is reflect light at the same angle as the surface it hits; diffuse reflection is to shine a light on an object and reflect it in many different directions. red bird clinic sallisaw oklahoma https://michaeljtwigg.com

WebThis shows that it is possible to obtain a high retroreflection power efficiency at an angle of choice using a very simple (slot or patch) metasurface design. The proposed design methodology allows one to achieve not only retroreflection but also reflection to arbitrary angles, with very high efficiency, which diversifies its uses.
