In recent years there has been a large body of work investigating periodic metasurface microwave absorbers. However, surprisingly few investigations have focused on the absorption performance similar non-periodic designs. this work, electromagnetic response area (310 mm x 310 mm) absorber that lacks global periodicity is experimentally studied. The top metallic layer ultra-thin (0.3 structured ...

The European fusion reactor research facility, called International Thermonuclear Experimental Reactor (ITER), is one of the most challenging projects that involves design and testing hundreds separately designed elements peripheric modules. One core involved in plasma heating are gyrotrons. They used as a microwave source electron–cyclotron resonance systems (ECRH) for variable injection RF po...

Microwave absorbing materials are usually designed to solve protection against electromagnetic interference in wireless communication systems and high frequency circuit mechanisms. In this research polystyrene (PS) nanocomposites containing various nano-fillers were successfully synthesized. The novelty of this work is comparing of three various nanostructures: non-metallic conductive graphene ...
