Abstract :
A combination of perfect electric conductor (PEC) and artificial magnetic conductor (AMC) cells with a periodicity around lambda can be applied to improve the RCS, by reducing the power scattered in the specular direction. A 180deg phase difference is created between the contribution from the PEC and AMC cells, obtaining destructive interference. A theoretical model is presented based on array theory which agrees with the simulated results using the commercial software Ansoft HFSS. The structure has been breadboarded and tested. Results match the predictions and will be presented at the conference.
