Abstract

The invention discloses a cross coupling magnetic saturation nonlinear transmission line structure comprising a coaxial rectangular external cylinder, an external cylinder cover and a coaxial internal core. The rectangular external cylinder and the external cylinder cover are fixedly connected as a whole via screws, and the rectangular external cylinder is internally provided with a sealing space. The coaxial internal core is arranged in the rectangular external cylinder, and the rectangular external cylinder is internally filled with transformer oil. The coaxial internal core comprises multiple metal block internal cores, ceramic dielectric blocks and conductor rods. The metal blocks are symmetrically and evenly distributed at the upper side and the lower side of the coaxial line. The conductor rods are successively connected between the metal blocks arranged at the upper side and the lower side of the coaxial line from input to output of the coaxial internal core. The ceramic dielectric blocks are arranged between the metal blocks arranged at the upper side or the lower side of the coaxial line. The external surface of a glass tube is sleeved by a ferrite magnetic core. The cross coupling magnetic saturation nonlinear transmission line concrete structure with high power capacity can be constructed so that generation of high-power radio frequency pulse can be realized, and a technical problem of generating high-power microwave by utilizing the nonlinear transmission line can be solved.

Description

technical field [0001] The invention relates to the technical field of high-power microwaves, in particular to a cross-coupled magnetic saturation nonlinear transmission line structure. Background technique [0002] Nonlinear transmission line (NLTL) is currently one of the effective ways to generate electromagnetic pulses in high power microwave (HPM) radiation devices. It utilizes the nonlinear and strong dispersion characteristics of magnetically saturated NLTL, and can directly convert the fed-in high-voltage long pulse into a radio frequency pulse output. Compared with traditional HPM devices, it has the advantage that it does not need to drive electron beams, confinement magnetic field systems and vacuum systems. At the same time, the center frequency and phase of the output electromagnetic pulse can be adjusted by setting the initial state of the inductive magnetic core, so that spatial power synthesis, beam scanning and frequency dynamic adjustment can be realized. ...
