Wideband 3D Frequency Selective Engineered Structures in the Terahertz Regime

A frequency selective engineered structure (FSES) using fragmented design procedures is presented that operates in the THz frequency range. The design improves upon a previous split ring resonator (SRR) design that leverages Membrane Projection Lithography (MPL) to achieve the desired feature size. Simulation results of the FSES are presented and compared to the SRR in regards to bandwidth and absorption properties across frequency; wideband performance is predicted for the 3D FSES.
