An Active Polarization-Insensitive Ultrathin Metamaterial Absorber with Frequency Controllability the proposed absorber is a fourfold symmetric structure consisting Jerusalem cross mounted with four pin diodes within the square ring. By switching the four diodes ON/OFF all at a time, the response of absorbance of this metamaterial structure switches from single-band to dual-band with polarization-insensitive characteristic.

Low-Complexity Side Information-Free Novel PTS Technique for PAPR Reduction in OFDM Systemsique eliminates the exhaustive search required for finding optimum phase factors as in conventional partial transmit sequence (C-PTS). Simulation results show an excellent improvement in PAPR reduction by level shift PTS as compared to C-PTS.
