Abstract: A terahertz waveguide bandpass filter block assembly including a waveguide iris filter, a pedestal block having a pedestal channel including a first one-half portion of the iris filter, and a cover block having a cover channel including a second one-half portion of the iris filter, where the first and second one-half portions combine to define the iris filter having a plurality of poles when the pedestal block and the cover block are secured together. The assembly also includes first and second ribbon strips positioned on opposing sides and adjacent to the iris filter between the pedestal block and the cover block, where a compression force between the pedestal block and the cover block compresses the first and second ribbon strips and sets an “a” dimension of the iris filter to tune the filter to a frequency band of interest.
