Research on absorbing properties of the concrete shielding material at 3mm wave bands

Abstract

The concrete was made from standard sand, steel fiber, iron ore-sand, carbon-fiber felt, ZnO whisker, ferrite, acetylene gas black, carbonyl iron, so that the concrete shielding material has the microwave absorbing performance. The aim is to search for a new protection method for grand buildings and martial building constructions. The concrete shielding material is first analyzed in the 3mm waveband. The paper focuses on the different absorption characteristic of concrete with different material and different content. The relation of content is discussed. It is guide for the future research.
