Abstract

The invention discloses an apparatus and method for generating (0.1-1T) terahertz continuous waves. The apparatus for generating the (0.1-1T) terahertz continuous waves (0.1T-1T) comprises a microwave generator 1, a primary transformer 2, an inner reflector 3, a secondary transformer 4 and a terahertz continuous wave compression cavity 5. The method for generating the (0.1-1T) terahertz continuous waves comprises the following steps: when the microwave generator 1 is started, microwaves generate induction currents at the surface of a metal braided conductive network of the primary transformer 2, the induction currents generate transient projection and recess motion when passing through each cross point of the metal braided conductive network, during such a motion process, one to multiple photons of the terahertz continuous waves are emitted, the effect of the inner reflector 3 is to send unconverted microwaves to the primary transformer 2 for continuous conversion through reflection, the effect of the secondary transformer 4 is to further convert residual microwaves going out of the inner reflector 3 to the terahertz continuous waves, and the effect of the terahertz continuous wave compression cavity 5 is to constraint the terahertz continuous waves to reach maximum concentration in one cavity and perform outputting outwards through an unlatching door.

Background technology

In biology, agricultural, medical science, the field such as physics suffers from being widely applied 0.1T-1T THz continuous wave, but mesh Front big less than power, the generator at price bottom, the majority having at present is the single pulsed Terahertz power generator of frequency, Power is little and expensive, such as following several method：

Focused on by ultrashort pulse light laser, beat and make air ionization in the gap of parallel conductive plates, and make ion-conductance Piemarker and electron charge form huge density contrast, produce electromagnetic transients thus width projects THz wave, frequency approximate number T, mean power About microwatt.

By the aerolite with microcellular structure and certain ionic conductivity for the heating, zeolite, infrared ray can excite one slightly Hole forms the continuous THz wave of electromagnetic oscillation and width injection 0.1T-1T, but power very little.

Free electron is accelerated to certain high-energy by rheotron, enters electromagnetic oscillation chamber and produce bistable electromagnetic Vibration, and launch the terahertz-wave pulse of single-frequency, pulse power is several watts, mean power about Bo watt.

Content of the invention

It is an object of the invention to proposing a kind of device of generation 0.1T-1T THz continuous wave and production method, including Microwave generator 1, one-stage transfor-mation device 2, inner reflector 3, two-dimensional transform device 4 and THz continuous wave constraint chamber 5.

It is hundreds of MHz sums GHz that described microwave generator 1 can produce frequency, and power is the microwave of hundreds of W to tens of KW.

Described one-stage transfor-mation device 2 weaves conductive mesh by several layers to tens of layers non-ferromagnetic metal and forms, and its side is input End, against the microwave transmissive openings of microwave generator 1, opposite side is outfan, opens in described constraint chamber 5, its effect be by Microwave is converted into THz continuous wave.

Described inner reflector 3 presses close to encase one-stage transfor-mation device 2 by 3 millimeters to several millimeters heavy insulation medium, and its effect is logical Cross reflection non-switched microwave send back to one-stage transfor-mation device 2 proceed conversion.

Described two-dimensional transform device 4 weaves conductive mesh by one layer to several layers non-ferromagnetic metal and forms, and its effect is to run out of The electromagnetic wave of the residual microwave of inner reflector 3 and other forms is converted further into THz continuous wave.

Described THz continuous wave constrains the closed cavity that chamber 5 is made for ferromagnetic material for shell, and its effect is to constrain too Hertz continuous wave is in a closed cavity.

The microwave that microwave generator produces is transformed into 0.1T-1T too after non-ferromagnetic metal weaves conductive mesh changer Hertz continuous wave, has a preliminary calculating below：Assume that 2.45G microwave weaves 2.5 centimetres of conductive mesh in non-ferromagnetic metal In the range of produce surface (X/Y plane) induced current density j, in a cycle it had altogether away 2.5 centimetres take advantage of 2 be equal to 5 lis Rice, for 100 mesh knitted conductor nets, each mesh about 0.17mm, have in the Z-direction of the node of mesh one recessed Convex, if in one cycle surface current j pass by altogether how many concavo-convex？I.e. 5 centimetres are equal to 294 divided by 0.017 centimetre, at this moment Surface current sends the frequency of THz wave in each concavo-convex motor process, and to be multiplied by 294 equal to 720G for 2.45G be 0.72T (wavelength of the microwave of 2.45G is approximately 10 centimetres here, its faradic current j knitted conductor net surface a cycle walk away from From be approximately wavelength half be 5 centimetres).

Because knitted conductor online surface induced current density j is affected by surrounding direction, in a cycle it Through scope be uncertain, therefore, the frequency that changer sends THz wave is continually varying in certain scope.
