Estimating the term…
The present invention describes a bolometric device with receiving cavity for measuring a beam of high frequency microwaves, comprising a hollow body (1) with receiving cavity (50) having an opening (2) for the entrance of said beam of high frequency microwaves in said receiving cavity (50), a diverging mirror (3) located in the lower part of said cavity (50) for reflecting said beam of microwaves on an absorbent coating material (4) applied on the internal surface (5) of the hollow body (1), a cooling circuit (7) for transferring the thermal energy accumulated on the absorbent coating material (4) and a circuit (6) for measuring the power of the beam of high frequency microwaves entering the hollow body (1). Said absorbent coating material (4) consists of boron carbide. In addition a procedure is described for coating with an absorbent material the internal surface (5) of a hollow body (1) being part of the aforementioned device for measuring a beam of high frequency microwaves (FIG. 1).
