Verification of Metal-Mesh Filter Response via ANSYS HFSS Simulation

Metal Mesh Filters (MMFs) are advantageous for use in the THz regime. An MMF was previously fabricated using a novel laser ablation technique. To validate the fabricated filter's response, and thus the fabrication technique, a model of the filter is created in ANSYS HFSS and the transmission response simulated. The model matches the geometry and material properties of the fabricated filter, making use of boundary conditions to simplify computation. The model simulation shows similar response to the measured filter's response, validating the fabrication technique. Considerations for future use and development of the simulation are discussed.
