Abstract

The invention discloses an electromagnetic wave polarization and filtering system and method. The electromagnetic wave polarization and filtering system consists of a conductor plate and a plurality of rectangular holes penetrating through the conductor plate, is simple in structure, and is low in preparation difficulty. The electromagnetic wave polarization and filtering system can simultaneouslyrealize polarization and filtering processing of electromagnetic waves of which the incident angle is less than a first preset value, and realizes the purpose of obtaining electromagnetic waves of apreset frequency and a preset polarization direction according to different requirements. In addition, the change of the polarization direction of the emitted electromagnetic waves can be realized byrotating the conductor plate in the horizontal plane. Compared with the mode of filtering and polarizing electromagnetic waves by using a filter and a polarizer in the prior art, the mode of filteringand polarizing electromagnetic waves by using the electromagnetic wave polarization and filtering system is easier to implement and more convenient to operate.

Description

technical field [0001] The present application relates to the field of electromagnetic technology, and more specifically, to an electromagnetic wave polarization and filtering system and method. Background technique [0002] Frequency and polarization direction are the two most basic attributes of electromagnetic waves. In practical applications, it is usually necessary to select electromagnetic waves with specific frequencies and specific polarization directions according to specific application scenarios, which is why filters and polarizers are produced. . However, the structures of filters and polarizers in the prior art are relatively complicated, and filtering and polarization generally cannot be realized at the same time. Contents of the invention [0003] In order to solve the above technical problems, the present application provides an electromagnetic wave polarization and filtering system and method, so as to achieve the purpose of reducing the structural comple...
