Microwave Absorbing Material Using Rubber Wood Sawdust

Abstract - A flat microwave absorber working at frequency 1.8GHz was developed by impregnation of activated carbon and polyurethane. The activated carbon is prepared from the conversion of rubber wood sawdust through chemical activation process using ZnCl2 solution as the precursor agent. Th...
