Abstract
The invention discloses a tunable signal modulator based on a multilayer stacked dielectric structure. The modulator comprises a signal emitter, a micro motor, a signal receiver, a bias voltage controller and a dielectric layer. The signal transmitter, the signal receiver and the bias voltage controller are electrically connected with the micro motor; the bias voltage controller is also electrically connected with the dielectric layer; the dielectric layer comprises a plurality of layers of dielectric groups which are stacked in sequence; each dielectric group comprises a dielectric A, a hyperbolic material P and a dielectric B which are arranged in sequence; and the hyperbolic material P is formed by stacking a dielectric C and graphene. The tunable signal modulator has the advantages ofsmall size, programmability, adjustability, strong stability and multiple functions, and belongs to a high-performance signal modulation device. Modulation of dynamic signals in different directions and different frequency bands can be realized by stacking different dielectric materials.
Description
technical field [0001] The invention relates to a tunable signal modulator based on a multilayer stacked dielectric structure, which belongs to the field of electronic communication. Background technique [0002] In recent years, with the rapid development of the communication technology industry, the required signal mode modulation equipment is developing in the direction of miniaturization and multi-function. At present, the frequency doubling method based on the electro-optical modulator to generate microwave signals can be divided into intensity modulation method, phase modulation method and polarization modulation method according to the modulation method. This method has good tunability and high stability, but it cannot realize small-angle reflection , Large-angle transmission function. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a tunable signal modulator based on a multi-layer s...
