Abstract

The invention discloses a hemispheric lens matrix terahertz wave source with a novel material structure. An RTO matrix consisting of a plurality of RTO emitting units is arranged on the lower surface of a hemispheric lens and is positioned in the center of the lower surface of the hemispheric lens. The RTO matrix is a matrix consisting of 2*2-32*32 RTO emitting units. The width of a waveguide formed by the hemispheric lens matrix terahertz wave source with the novel material structure is different from that of an oscillator, and therefore a standing wave is formed between the oscillator and the waveguide. An RTD is connected with an upper electrode of the oscillator through a heat sink, and meanwhile, by changing the position of the RTD in the oscillator, oscillation of the oscillator in different frequency bands can be achieved. Due to the fact that the waveguide transmits a high-frequency electromagnetic wave and the loss is extremely low, a terahertz wave passes through the waveguide, then enters a slot antenna or a rectangular micro-strip patch antenna and is emitted finally, so that horizontal or vertical communication between chips is achieved. Under the current process conditions, the process difficulty does not need to be increased, and the power of RTO can be improved by more than ten times to few ten times.

Description

technical field [0001] The invention relates to a hemispherical lens matrix terahertz wave source. In particular, it relates to a hemispherical lens matrix terahertz wave source with a new material structure composed of a plurality of single-tube terahertz wave sources with a new material structure forming a matrix and a coplanar lens. Background technique [0002] Since the 0.3-10 terahertz wave can strongly penetrate substances such as plastic, paper, wood, human body, atmosphere, etc., it can be widely used in security scanning, radio astronomy, biological remote sensing, production monitoring and other fields, specific classification This can include mail scanning, paper production, plastic welding inspection, ancient painting analysis, human perspective, food quality inspection, skin cancer classification, etc. To realize the above technologies, it is necessary to provide a high-power terahertz wave source or a terahertz generator, and at the same time be equipped with...
