A meta-surface-based arbitrary bandwidth filter realization method for terahertz (THz) future
communications is presented. The approach involves integrating a meta-surface-based …

The directional optimization correction (DOC) method is proposed to reduce the
performance error between desired and fabricated terahertz (THz) devices. Three 340 GHz …

The design of a fourth-order centrally corrugated double-folded hairpin line bandpass filter
with a broad stopband and enhanced selectivity is demonstrated in this article. Initially, a …

A band-pass hairpin filter is proposed that is combined with two C-shaped defected ground
structures (DGSs) to provide a wide rejection band. The top layer of the structure consists of …

The present article describes the design of a compact fourth-order centrally corrugated
hairpin line bandpass filter with an improved skirt characteristic and an extended stopband …
