ELECTROMAGNETIC WAVE SENSOR, IMAGING ELEMENT AND IMAGING DEVICE |
摘要 |
The present invention enables to provide a simple and inexpensive electromagnetic wave sensor that selectively detects sub-millimeter waves and millimeter waves in a specific frequency band, an imaging element and an imaging device. The distance of the gap between a plurality of antenna elements is smaller than the wavelength of infrared light. A capacitor electrically formed by the gap between the plurality of antenna elements, and an electrical resistor portion form parallel circuits electrically coupled to the antenna portion. The plurality of antenna elements are formed so that the impedance of the antenna portion is matched with the impedance of the parallel circuits against electromagnetic waves having a predetermined frequency, and is not matched against the higher harmonics of electromagnetic waves having the predetermined frequency. |
