Numerical analysis and test of pyramidal HF absorber International Conference Applied Electronics

The paper presents numerical analysis of the microwave absorber design. It is possible to use modified concept of the absorber. Modified absorber has appropriate properties and it is possible to use it in non-reflecting chamber construction. The non-reflecting chamber will be used for open space testing of relativistic microwave pulse generator; P_max=500 MW, t_p=10-100 ns. Presented work is a part of the project conducted in co-operation with VTUPV Vyskov, PROTOTYPA a.s. and TESLA Vrsovice Praha. An experimental testing of the proposed pyramidal absorbers was done in the laboratories located at UD Brno.
