在超材料吸收器（MA）的现代时代，许多实现通常在C和X微波波段中。遗传编程（GP）软件被用来生成新的三维设计的超材料吸收剂与多层介质，以实现高宽带吸收率的紧凑雷达波段（CRB）（1-11 GHz）没有损耗材料。GP以前用于创建具有225-450 MHz宽带能力的人工磁导体（AMC），而无需磁性或吸收材料。利用GP的能力，以创建宽带结构，GP软件进行修改，以创建宽带MA。两个2D图案化的结构与多层薄膜产生了超过90%的吸收率峰值附近的3和5 GHz。初步使用GP创建宽带MA结构显示了创建拓宽整个CRB的结构的良好潜力。
In the modern age of metamaterial absorbers (MA), many implementations are generally in the C and X microwave bands. Genetic programming (GP) software is used to generate new 3D designs for metamaterial absorbers with multilayer dielectrics to achieve high broadband absorptivity in the compact radar band (CRB) (1–11 GHz) without lossy materials. GP was previously used to create an artificial magnetic conductor (AMC) with broadband capabilities in 225–450 MHz without magnetic or absorbing materials. Utilizing the capabilities of GP to create broadband structures, the GP software is modified to create broadband MAs. Two 2D patterned structures with multilayer dielectrics were generated with above 90% absorptivity peaks around 3 and 5 GHz. The preliminary use of GP to create broadband MA structures shows excellent potential for creating a structure that broadens the whole CRB.
