Abstract: A light-receiving device having an electromagnetic interference removal function is provided. The light-receiving device includes a waveguide-shaped structure that extends in a traveling direction of photons and high-frequency electromagnetic waves incident on a light-receiving area and that surrounds the light-receiving area, and an insulating layer configured to fix the waveguide-shaped structure.

Abstract: A probe antenna, a probing system, and a power density measuring method to measure a power density of a near-field electromagnetic field are disposed. The probe antenna includes a board, and a conductor transmitting line formed on the board, having a constant line width, and formed in a polygonal shape or in a closed-curve shape. The conductor transmitting line is divided into a first transmitting line and a second transmitting line that are separated from each other, and includes a first receiving port formed with one end of the first transmitting line and one end of the second transmitting line and a second receiving port formed with another end of the first transmitting line and another end of the second transmitting line.
