چکیده
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 power into ring. In this work, development application an alumina-titania 60/40 mixed oxide ceramic absorber coating on copper cylinder described. part dummy load gyrotron its purpose to absorb radiation generated by gyrotrons during phase. applied means atmospheric spraying (APS). deposited inner diameter one-meter cylindrical tube. To ensure homogeneous absorption when incoming beam repeatedly scattered along tube surface, shows varying thickness function length. By it ensured thermal distributed homogeneously entire surface. This paper describes modeling approach distribution, manufacturing concept internal spray characterization with regard microstructure characteristics.

A Planar, Layered Ultra-wideband Metamaterial Absorber for Microwave Frequencies
In this paper, an ultra-wideband metamaterial absorber is designed and simulated. The proposed absorber is planar and low profile. It is made of a copper sheet coated with two dielectric layers. Each unit cell of the metamaterial structure is composed of multiple metallic split rings, which are patterned on the top and middle boundaries of the dielectrics. The designed absorber utilizes differe...
