Electromagnetic wave interaction and beam steering in plasma medium

This paper presents the effects of electromagnetic wave interaction with plasma medium and its application for wave manipulation as a use-case scenario. An efficient one-dimensional (1D) finite-difference time domain (FDTD) approach is used to model the wave propagation through the plasma medium at different plasma densities in transmission mode and reflection mode backed by a perfect electric boundary. Furthermore, the beam steering properties of the plasma for an incoming wave are studied and the results are reported. This study supports the development of plasma based reconfigurable surfaces, offering advantages in tunability, stealth and adaptive system designs.<br/><br/>
