Abstract :
The author found that a wide variety of reflection and transmission filters based on guided-mode resonance effect can be designed utilizing direct and inverse methods that include diffraction theory, waveguide theory and electromagnetic interference concepts as well as genetic algorithms to solve inverse problems. These filters might be useful in microwave communication applications due to their attractive features that include high-efficiency, low loss, low cost, and flexibility in obtaining the desired filter-response specifications.
