Key Points

Develop an optimization method combining genetic algorithms and geometry refinement to design easily fabricated, single-layer multiband frequency selective surfaces.
Integrated a genetic algorithm with a geometry-refinement technique that explicitly enforces physical connectivity constraints among element structures.
Optimized a single-layer surface geometry configured to transmit L band (1.5 GHz) and S band (2.5 GHz) while reflecting Ka band (20/30 GHz) frequencies.
Fabricated a prototype and evaluated performance by comparing numerical electromagnetic calculations directly against experimental transmission measurements.
Generated an optimized single-layer frequency selective surface exhibiting broader operational bandwidths than existing conventional designs.
Demonstrated close agreement between calculated and experimentally measured transmission responses across all target passbands and stopbands.
