Embodiment Construction

[0027] The present invention will be further described below in conjunction with embodiment and accompanying drawing.

[0028] Compared with the traditional tunable artificial electromagnetic material device, the DC optical control device works in the DC frequency band to realize the stealth of the DC field. In the embodiment of the present invention, the entire device structure presents a ring shape, and the basic framework is composed of 13 layers of resistor networks. The resistors on each layer are divided into radial and tangential resistors, and the radial and tangential resistors on the same layer The values ​​are different, and the radial and tangential resistances of different layers are also different. On the same layer, all radial resistances have the same resistance value, and all tangential resistances have the same resistance value. The fan-shaped area on the third and fourth layers from the inside to the outside is the light control area, and the same photoresis...

Abstract

The invention discloses a photocontrol direct-current conversion device, which comprises a resistor network and photo-resistors and is remotely controlled by illuminating visible light. Most traditional regulatory structure devices are high in working frequency range, narrow in frequency band and not easy to process. The photocontrol direct-current conversion device disclosed by the invention works in an electrostatic field; the excitation mode is simple; and an artificial electromagnetic material unit structure is realized by a negative resistance form in anisotropic distribution, so that the photocontrol direct-current conversion device has novel performance characteristics. According to the photocontrol direct-current conversion device, the resistance values, namely tensor forms of the resistors, of distributed resistors in various directions are firstly calculated by the transforming optics principle; and the photo-resistors are arranged on a tensor resistor in parallel, and can be controlled by visible light, so as to realize a multifunctional direct-current photocontrol unit structure. In addition, profiting from excellent characteristics of the novel artificial electromagnetic material, the unit structure also has excellent performance such as high stability and wide working frequency range.

Description

technical field [0001] The invention relates to a light-controlled conversion device for a direct current field, belonging to the field of novel artificial electromagnetic devices. Background technique [0002] As a new type of medium, the new artificial electromagnetic material has characteristics that are incomparable to natural materials. Its dielectric constant and magnetic permeability can be adjusted artificially in a specific frequency band. In addition, under the guidance of the theory of transformation optics, researchers have developed many transformation devices, and most of them can be manufactured using new artificial electromagnetic materials. However, most of the previous research on new artificial electromagnetic materials stayed in time-harmonic fields, and there were few researches on electrostatic fields or static magnetic fields. The cloaking device of the time harmonic field has a narrow operating frequency band, and the size of the cloaked object is al...
