Abstract: The paper derives the throughput of simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STARRIS) with hybrid wind and radio frequency (RF) energy harvesting. The harvested power from wind depends on the power of three of wind speed. The wind speed has a Weibull distribution. The harvested power from RF signals depends on the power of the received signal. We evaluate the throughput of STARRIS with hybrid power harvesting from wind and RF signals. Transmission is performed to users U_t and U_r of STARRIS. The effect of the number of STARRIS reflectors is studied for Rayleigh channels. The use of N = 16, 32, 64 elements offers up to 15, 30 and 45 dB gain versus N = 8. The major difficulties and challenges is to derive the throughput of STARRIS using both wind and radio frequency (RF) energy harvesting.
