Abstract

In this study, a new terahertz cross-shaped metamaterial bandpass filter is designed, simulated and fabricated. Among the properties of the proposed filter, compared to built-in filters (especially cross-shaped filters), one may refer to higher output transfer intensity (of almost 100%) and less noise effects (unwanted frequencies) in the whole range of 0.1 to 3 THz. The simulation is conducted by the CST STUDIO software and the FDTD method. Experimental results with THz-TDS system and simulation results with CST STUDIO software that are well matched.
