Round hollowed-out branch structure terahertz wave polarization beam splitter

Abstract

The invention discloses a round hollowed-out branch structure terahertz wave polarization beam splitter which comprises a signal input end, a first signal output end, a second signal output end, a left side first hole area, a left side second hole area, a round hole area, a right side first hole area, a right side second hole area, a single-row beam splitting hole area, a small hole hollowed-out area, a second large hole hollow-out area and a base body. The round hole area is composed of a concentric round hole hollowed-out area, an opening ring hole area and an arc hole area which are distributed outwards from the center of the round hole area. Signals are input from the signal input end, and beam splitting wave can be respectively output from the first signal output end and the second signal output end. The round hollowed-out branch structure terahertz wave polarization beam splitter has the advantages of being simple in structure, high in beam splitting rate, small in size, small in volume, low in cost and the like, and meeting application requirements of fields of non-destructive detection, medical analysis, terahertz wave wireless communication and the like.

Description

technical field [0001] The invention relates to a beam splitter, in particular to a terahertz wave polarization beam splitter with a circular hollow branch structure. Background technique [0002] Terahertz waves (also known as THz waves, T-rays) usually refer to electromagnetic radiation with a frequency in the range of 0.1-10 THz, which is located between microwaves and infrared rays on the electromagnetic spectrum. The THz frequency band is the last electromagnetic radiation region that is of great scientific value but has not been fully understood and utilized. For many years, due to the lack of practical THz wave generation methods and detection methods, the characteristics of the THz band have been poorly understood, so that this band has been called the "THz gap" in the electromagnetic spectrum. The frequency range of terahertz waves is at the intersection of electronics and photonics. In the long-wave direction, it overlaps with millimeter waves; in the short-wave ...
