Cloaking electromagnetic wave with phase shifter

When electromagnetic wave is normally reflected from semi-infinite denser medium, the phase of reflection wave jumps π, when electromagnetic wave is normally reflected from finite thickness denser (or thinner) medium, the phase of the reflection wave will change. According to the electromagnetic wave theory, we designed phase shifter and derived the reflection coefficient and the phase shift of the reflection wave. By comparing phase, we designed phase compensation cloak. The simulation results show that the phase shifter can cloak electromagnetic wave.
