The Microwave Energy Harvesting by Absorbent Structures Based on Composite Materials

Abstract

—This study presents two types of Salesbary Screen models which can be used for the microwave EMR harvesting in the occupational areas for the prevention case of the EMF impact for human health. The proposal structures operate on the 618GHz frequency electromagnetic radiation and allow collecting heating energy of the defined range. There are two types of fillers of 3% MWCNTs and 3% CNFs where considered in meaning of well electromagnetic radiation absorbency properties. The special attention had been paid for the outer, spacer and back layers thickness evaluation. The specific power as well as the total power in the proposal structures were calculated
