Abstract :
An optimization technique based on the microgenetic algorithm (MGA) is presented for the design of multilayered radar absorbing materials made of tetrapod-shaped ZnO whisker in this paper. The fast optimization procedure is designed for a given maximum thickness and the optimization conditions are different in order to meet the practical requirements in the different frequency bands (the range of 2∼18GHz). The effects of the thickness, the number of layers, and the restrained conditions on the optimization results are discussed in detail.
