ABSTRACT
Microwave energy reception approach for space solar power satellite applications .Concept of artificial perfectly matched layer.Embedding rectifying diodes into well-designed metamaterial cells.Obtained rectifying surface simultaneously exhibits a nearly perfect impedance matching to the air and the rectifying circuits, and a strong impedance mismatching to the air at harmonic frequencies.Simple structure that can be implemented using commercial multi-layer printed circuit board technology.Rectifying surface has free-space wavelength.Power absorption rate of 99.92% under normal incident power, density of 0.1 mW/cm, and a 56.16-dB.
INTRODUCTION
Convert direct solar radiation into electrical power and transmit it wirelessly to the earth. In all SSPS schemes.Transmit gigawatt power to the earth, and huge rectenna arrays Occupying areas up to tens of square kilometers are used to receive and rectify microwave energy into dc power . Rectennas have been considered as mature and well-functional They are non ideal options for SSPS applications. Combining conventional antennas (or array antennas) and rectifying circuits. Rectennas have the same limitations of traditional antennas.
