Abstract:
Passband filters in the THz frequency range devices are one the most useful application of metamaterials to cover the so called THz gap. A design procedure to obtain THz filters with a broad transmission bandwidth is proposed. We apply the powerful and versatile Periodic Method of Moment (PMM) to evaluate the response of the metamaterial. The design is optimized by adopting a genetic algorithm to reach the target filter performance at a passband frequency centered at 1.25 THz. Two different solutions based on a single and a double frequency selective surface based on a low cost mylar substrate are compared. Herein we also plan to fabricate our design by applying UV-photolithography process to demonstrate the excellent performance.
