چکیده :

A Reconfigurable intelligent surface is considered with unit-cells connected to the ground by proper PIN diodes. Through unit-cell design the reflection coefficient of the cells is optimized for the ON and OFF states. The progressive phase between the unit-cells is determined by the analytical phase shift relation of the conventional phased array theory and then discretized to 0 and π levels. This way the optimized reflection direction is realized. The numerical results are compared to the analytical ones obtained through conventional two-dimensional phased array approximation.
