Application of the micro-genetic algorithm to the design of spatial filters with frequency-selective surfaces embedded in dielectric media

Application of the micro-genetic algorithm to the design of spatial filters with frequency-selective surfaces embedded in dielectric media

We present an efficient method of optimizing spatial filters comprising of single and multiple frequency-selective surface (FSS) screens embedded in multilayered dielectric media. Two such filter designs are optimized via the micro-genetic algorithm (MGA) and their frequency responses are validated...

Zusammenfassung:We present an efficient method of optimizing spatial filters comprising of single and multiple frequency-selective surface (FSS) screens embedded in multilayered dielectric media. Two such filter designs are optimized via the micro-genetic algorithm (MGA) and their frequency responses are validated by alternate methods.
