Abstract

In this work metamaterials (MTMs) are applied for optimal design of filters in terahertz frequencies. These MTM filters are designed for different applications. The random hill climbing (RHC) optimization method is used to find optimal structures. Periodic method of moments (PMOM) is applied to calculate the fitness function of the resulted structures from RHC optimizer. The PMOM simulation results are compared with Ansoft HFSS12 CAD outcomes. They confirm the validity and accuracy of the written PMOM code. The computation time of the PMOM code versus HFSS CAD is extremely low which assures the efficiency of the PMOM for the planar periodic structure analysis.
