Abstract

The invention discloses a designing method of a millimeter wave varied box type window. The designing method comprises the following steps of: S1, determining a type and a size of a rectangular waveguide and a diameter of a round waveguide according to the scope of an operating frequency of a microwave window; S2, selecting a material, a diameter and a thickness of a medium window plate; S3, determining whether the material, diameter and thickness of the medium window plate, which are selected in the step S2, meet matching conditions by utilizing a microwave network theory; S4, determining a length of the round waveguide by using the microwave network theory; S5, determining whether the transmission characteristic of the millimeter wave varied box type window meet the demand by using the microwave network theory; and S6, carrying out modeling and performance analysis on the determined millimeter wave varied box type window by using three-dimensional electromagnetic simulation software so as to obtain the millimeter wave varied box type window which meets the performance requirements. According to the invention, the millimeter wave varied box type window which meets the specific performance requirements can be accurately and quickly obtained and an effective method is provided for the quick and efficient design of a high-performance microwave energy transmission window.

Description

technical field [0001] The invention belongs to the technical field of input and output windows of microwave vacuum electronic devices, and in particular relates to a design method of a millimeter-wave variant box-type window. Background technique [0002] Millimeter wave refers to the electromagnetic spectrum with a frequency between 30GHz and 300GHz, which has the advantages of wide frequency band, narrow beam, all-weather and miniaturization.
