Input Impedance of Planar FP and EBG Antennas [PDF]
2007 Loughborough Antennas and Propagation Conference, 2007 The theoretical study of the input impedance for Fabry-Perot (FP), Electromagnetic Band Gap (EBG) or Leaky Wave (LW) antennas is a real challenge from mathematical and electromagnetic modelling point of view and is very rarely addressed in the literature.

High-Efficiency Dual-Band Rectifier with Extended Dynamic Frequency Ranges based on Independent Dual-Band Impedance Control [PDF]
Journal of Electromagnetic Engineering and ScienceThis study presents a high-efficiency dual-band rectifier with an extended frequency range. The proposed rectifier comprises a voltage doubler with shunt capacitors and an independent dual-band impedance control network (IDICN). The proposed IDICN, which
