N2 - This paper proposes a 1-bit programmable metasurface which is capable of an adaptive beam focusing according to the receiver position. By doing so, the electromagnetic (EM) wireless power transfer (WPT) efficiency can be increased. The metasurface is designed to work at 5.8GHz and consists of 16 x 16 square unicell. Each of the unicells is connected with one pin diode that enables "ON"and "OFF"states with 1800 reflected signal phase change. The "ON"(0) and "OFF"(1) states correspond to the states of the pin diode. By adjusting the ON/OFF pattern of the metasurface appropriately, we can control the reflected impinging wave. Then, as a radio frequency (RF) choke, a butterfly stub has been designed. We also fabricate and implement a metasurface prototype to verify the ability of the metasurface. The results show that the metasurface is capable of steering and focusing the beam towards the receiver position.
