Abstract:
Provided is an electromagnetic wave power sensing apparatus. The electromagnetic wave power measuring apparatus includes a waveguide to which electromagnetic wave power is incident, an electromagnetic wave absorber disposed at a termination of the waveguide and absorbing the electromagnetic wave power incident to a front surface of the electromagnetic wave absorber, parallel plates disposed at a rear of the electromagnetic wave absorber and arranged on and under a center line of the waveguide, a waveguide guide for fixing the waveguide and the electromagnetic wave absorber, wherein the parallel plates are positioned in the waveguide guide, an electro-optic element configured to sense the electromagnetic wave power, an electro-optic element fixer to which the electro-optic element is coupled, and a movement guide coupled to the electro-optic element fixer and controlling movement of the electro-optic element into the inside of the waveguide guide in order to sense the electromagnetic wave power.
