Abstract Details

2014, Master of Science in Engineering (MSEgr), Wright State University, Electrical Engineering.
The design and characterization of metamaterials has emerged as a field of great interest in electromagnetics in recent years. The characterization has been accomplished primarily by means of fabrication, measurement, and parameter estimation. Previous work by Knisely and Havrilla [8] has shown that biaxial anisotropy can be created by machining air vias uniaxially into a homogeneous, isotropic material. This research project proposes a design method for manufactured biaxial materials. Full wave modeling and simulation is used for samples with varying via size, separation and pose to obtain the scattering parameters S11 and S21. To compare the simulated S-parameters to theoretical S-parameters of different dielectric values solved by mode matching, a cost function was created. The cost function is minimized using a constrained non-linear least squares optimization technique. When the global minimum of the cost function is found the material parameter for the values that optimized the function are estimated to be the values of the simulated material.
