Abstract
A terahertz band filter for filtering, in a frequency band, a terahertz wave propagating between a pair of metal plates with an upper parallel surface facing a lower parallel surface includes a sheet parallel to the upper and lower parallel surfaces, which is disposed between the metal plates and is spaced apart therefrom, and at least one slit located in the sheet to face the upper and lower parallel surfaces, wherein the sheet comprises a single slit to function as a notch filter for blocking in a specific frequency band.
Claims9
A terahertz band filter for filtering, in a frequency band, a terahertz wave propagating between a pair of metal plates with an upper parallel surface facing a lower parallel surface, the terahertz band filter comprising:
- a sheet parallel to the upper and lower parallel surfaces, which is disposed between the metal plates and is spaced apart therefrom;
- and
- a slit located in the sheet facing the upper and lower parallel surfaces, and
- wherein:
- the slit is formed only in a direction perpendicular to a longitudinal axis of the sheet;
- a length and a width of the slit are varied to control a resonant frequency of a notch filter;
- and
- the slit is the only slit in the sheet and is configured to function as a notch filter for blocking in a specific frequency band.
