Abstract :
We present a GA/FDTD optimisation technique and its application in the design of single and multi-band artificial magnetic conducting (AMC) surfaces. The technique is a combination of a genetic algorithm (GA) and the finite-difference time-domain (FDTD) method. For the efficiency purpose, a micro-genetic algorithm (MGA) is applied to optimize the geometry of an AMC unit cell, and the fitness functions are evaluated by the FDTD method. The effectiveness of the algorithm is demonstrated by designing two AMC surfaces: a single-band AMC at 5.5 GHz and a dual-band AMC at 5.5 GHz and 12.0 GHz
