The design of amorphous photonic material and photonic crystal devicements we design to make a reflecting mirror of cylinder paraboloid of an antenna by using amorphous photonic materials. we calculated the transmission of the mirror and the distribution of electric field by using multiple scattering method. the result shows that it can be used as a reflecting mirror of an antenna
非晶光子材料和光子晶體器件的設計提出了用介質圓柱光子晶體作微波天線的柱拋物面反射鏡，用多重散射方法計算了反射鏡的透過譜，並模擬計算了天線的電場分佈，初步認為可以用非晶光子材料作微波天線的反射鏡。 -
It used to apply only to reflecting telescopes in which the primary mirror was a paraboloid, and thus capable of forming an image all by itself
它過去只用在拋物面反射望遠鏡上，這種鏡子只用主反射鏡就能成像。
