Abstract

The invention relates to an extreme ultraviolet pulse generation modulator. The extreme ultraviolet pulse generation modulator comprises an electron source, a control grid, a focusing electrode and an anode target. Electrons are generated by the electron source, and the control grid is used for controlling the intensity of the electrons generated by the electron source to form electronic pulses. The electronic pulses are focused by an electric field formed by the focusing electrode, the anode target accelerates the electronic pulses, and the electronic pulses finally bombard the anode target to generate extreme ultraviolet pulse rays, wherein the wavelength range of the extreme ultraviolet pulse rays ranges from 10 nm to 200 nm.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an extreme ultraviolet pulse generation modulator. Background technique [0002] The research and application of wireless communication has covered radio waves, microwaves to infrared, visible light, ultraviolet and other electromagnetic waves. Driven by the observation technology of X-ray astronomy, the United States and China are carrying out research on the application of space X-ray communication. In theory, X-ray communication has many advantages such as good directionality, long transmission distance, strong confidentiality, no electromagnetic interference from the space environment, and wide communication frequency bandwidth. However, due to the high photon energy of X-rays, collimated emission and focused collection are extremely difficult. In particular, light weight and small volume collimation or focusing systems are still difficult to break through in the short t...
