Abstract: The single-pole Lorentz model parameters for Silicon-Germanium Alloy (1.5:1) and Cuprous Oxide are presented. An algorithm has been developed to optimize the parameters applicable to a broad frequency range. The obtained parameters have been used to determine the complex relative permittivity for these two materials. To verify the obtained results, they have been compared with experimental values and a very good agreement is achieved. The associated root-mean-square (RMS) deviations are observed to be 0.15 and 0.08 respectively. Finally a plasmonic waveguide based on Metal-Dielectric-Metal (MDM) configuration constructed with silver (metal) and Cuprous Oxide (dielectric) has been analyzed and presented.

Abstract: Inline with the advancement of low power circuit design, it has reduced the power requirements of electronic devices to the level of microwatts. As power demand decreases, the possibility of using energy harvesting systems as an alternative to batteries increases. However, for low power electronic application, the consistency of minimum voltage and current supply to the electronic devices is an important issue to be considered. This paper presents an outcome of DC-to DC step down IC MC34063A for harvesting energy using piezoelectric and electromagnetic. The simulation results of the circuit shows an output voltage of 3.3V with an input voltage of 5V from the micro-generators.
