example 1

[0020] Example 1: If figure 1 Shown is a schematic diagram of the structure of the terahertz wave optical focusing lens proposed by the present invention. It uses four "well" shaped metal rings, stacked and placed according to the center alignment, and glued to form a hollow structure to minimize the terahertz wave. transmission loss.

[0021] The "well" shaped metal ring is composed of a square ring and 8 rectangular blocks, the length, width and thickness of the 8 rectangular blocks are respectively equal, and the thicknesses are all equal to the thickness of the square ring. From the front to the back are the first ring 1, the second ring 2, the third ring 3 and the fourth ring 4, the thickness of the four "well" shaped rings are 2.2mm, 1.5mm, 1.1mm, 1.0mm; The inner edge distances of the square ring are 5.07mm, 8.78mm, 11.34mm, 13.42mm; the outer edge distances of the square are 7.17mm, 10.14mm, 12.42mm, 14.34mm; The lengths are 8.04mm, 5.07mm, 2.79mm, 0.87mm; the widths...

Abstract

The invention relates to a #-shaped stack type terahertz wave optical focusing lens and belongs to the optical component technical field. The #-shaped stack type terahertz wave optical focusing lens is a transmission type lens; the transmission type lens is of a hollow structure and is provided with at least three #-shaped metal rings; the centers of the #-shaped metal rings are aligned with and tightly attached to one another; and the maximum aperture size of the #-shaped metal rings is decreased progressively along the propagation direction of terahertz waves. According to the #-shaped stack type terahertz wave optical focusing lens, the stack hollow structure is adopted to realize a focusing function, and therefore, absorption loss can be significantly reduced, the strength of transmitted terahertz waves which have passed through the lens can be increased, and the divergence angle of the transmitted terahertz waves which have passed through the lens can be decreased. The #-shaped stack type terahertz wave optical focusing lens has the advantages of convenience in implementation and easiness in popularization and application.

Description

technical field [0001] The invention relates to the technical field of optical elements, in particular to a terahertz wave optical focusing lens. Background technique [0002] Terahertz waves are in the transition band from microwave to far infrared, with a frequency range of 0.1THz to 10THz, and a corresponding wavelength range of 3mm to 30μm. Compared with electromagnetic waves in other frequency bands, terahertz waves show many of their own characteristics and advantages, which can be applied to many disciplines and fields, mainly in the following aspects: (1) Terahertz communication, using Terahertz waves as carrier antennas are smaller in size for secure battlefield communications, and terahertz waves are more penetrable to smoke. (2) Terahertz imaging. Since terahertz radiation is non-ionizing, it only triggers the oscillation state of molecules, so the morphology and structure of molecules will not change after the radiation is withdrawn. Nevertheless, the applicati...
