Problems solved by technology

However, active RIS requires additional power supply, and RIS also introduces non-negligible dynamic noise
Therefore, RIS with a hybrid architecture combines the advantages of the two, consisting of passive reflective devices and partly active reflective devices connected to reflective amplifiers, arranged in a regular manner, but still requires power supply

Abstract

The invention discloses a hybrid reconfigurable intelligent reflecting surface capable of realizing solar self-power supply. The hybrid reconfigurable intelligent reflecting surface comprises a plurality of active reflecting elements, a plurality of passive reflecting elements and an RIS controller respectively connected with the active reflecting elements and the passive reflecting elements. The RIS controller is used for controlling the phase and the amplitude of an incident signal on the active reflecting elements, and controlling a phase of an incident signal on the passive reflective element; the active reflection element sequentially comprises an active reflection element layer, a semiconductor crystal layer, a chip inductance layer, a first metal backboard and a first control circuit board from top to bottom; and the active reflection element layer, the semiconductor crystal layer and the first metal backboard form a solar cell, and the solar cell can convert light incident to the active reflection element into electric energy so as to supply power to the first control circuit board and the RIS controller. According to the hybrid reconfigurable intelligent reflecting surface, the solar cell and the active reflecting element are integrated, the power supply problem is solved, and normal work at night can be achieved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a hybrid reconfigurable intelligent reflective surface capable of realizing solar self-power supply. Background technique [0002] At present, the integration of solar cells and communication antennas is a good way to realize miniaturization, energy saving, intelligence, portability, low cost and multi-function of wireless communication equipment. Solar energy is an inexhaustible green energy source. Since the successful development of practical silicon solar cells in Bell Laboratories in 1954, it has now developed into a huge solar photovoltaic industry. At present, the most mature development is the silicon battery technology, and its application range is also the widest. Silicon solar cells can be divided into monocrystalline silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cells according to the purity of silicon. Monocr...
