PROJECT TITLE :
A Fast and Efficient Design Method for Circuit Analog Absorbers Consisting of Resistive Square-Loop Arrays
This paper proposes a completely unique optimization design technique for circuit analog absorbers consisting of resistor-loaded square-loop arrays. Initial, new precise equivalent circuit models (ECMs) for square-loop-array-based absorbers are derived through the artificial asymptote method. The presented models are applicable for multilayered absorber with printed single or double SLAs on every layer. Then, the combination of this ECM and typical genetic algorithm (GA) is proposed and provided a fast and efficient method to style broadband and low-profile SLA absorbers. For demonstration, four absorbers are designed and optimized. Finally, the agreement between the simulated and measured reflection coefficients indicates the validity of the presented methodology.
