Waveguide measurements of biochar derived from sewage sludge

Abstract

Composites based on biochar derived from sewage sludge as filler in epoxy resin are fabricated and measured in a waveguide in C-band. Biochar is cheap, readily available and environmentally friendly and thus is a very good contender among other carbon-based materials for use in shielding applications. Biochar provide promising results in term of transmission of
