Abstract

The invention discloses a terahertz polarization regulating and control device. The terahertz polarization regulating and control device comprises a dielectric superstructure and a substrate. The dielectric superstructure is made from an all-dielectric material and comprises columnar dielectric units distributed periodically. The ratio of the long axis length of each columnar dielectric unit to the terahertz wave length to be adjusted is in a first preset interval; the ratio of the short axis length of each columnar dielectric unit to the terahertz wave length to be adjusted is in a second preset interval; the ratio of the height of each columnar dielectric unit to the terahertz wave length to be adjusted is in a third preset interval; the ratio of the separation distance of every two adjacent columnar dielectric units in the long axis direction to the terahertz wave length to be adjusted is in a fourth preset interval; the ratio of the separation distance of every two adjacent columnar dielectric units in the short axis direction to the terahertz wave length to be adjusted is in a fifth preset interval. The working efficiency of the device is improved, and a phase modulation rangeis widened. The invention also provides a manufacturing method of the terahertz polarization regulating and control device having the above advantages.

Description

technical field [0001] The invention relates to the field of terahertz, in particular to a terahertz polarization control device and a manufacturing method thereof. Background technique [0002] Terahertz radiation is electromagnetic radiation from 0.1 to 10 THz. From the perspective of frequency, it is between radio waves and light waves, millimeter waves and infrared rays; from the perspective of energy, it is between electrons and photons. The infrared and microwave technologies on the side are very mature, but the terahertz technology is basically still a blank. The reason is that in this frequency band, it is neither completely suitable for processing by optical theory, nor is it completely suitable for research by microwave theory. Terahertz systems are widely used in many fields such as semiconductor materials, properties research of high-temperature superconducting materials, tomographic imaging technology, label-free genetic inspection, cell-level imaging, chemical ...
