Newly Developed Bolometer Mounts for the Short Millimeter Wave Region

Two kinds of bolometer mounts have been recently developed at the Electrotechnical Laboratory (ETL) that are suitable for the millimeter wave region, especially for the short millimeter waves. They are 1) a matched-load-type bolometer mount and 2) a rising-sun-type bolometer mount. The former is the mount for measuring the rectangular waveguide power and the latter is for the circular TE01 mode waveguide power. Experimental mounts of both kinds have been designed and examined at 100 GHz. These mounts have demonstrated superior performance compared to those commercially available.
