After six years the closed-cell absorber with the perfect tip

Rik de Groot, the Managing Director of Dutch Microwave Absorber Solutions, and his team spent six years developing a closed-cell absorber with the perfect tip. But why is it so difficult to achieve this?
Re-inventing the microwave absorber models!

Our sister company, Dutch Microwave Absorber Solutions, invested six years in developing a pyramid-shaped absorber from expandable polystyrene (EPS).
More representative absorber reflectivity measurements

Is the radar cross-section method for absorber reflectivity measurements still representative? No, following the guidelines of IEEE1128, the NLR-Arch setup measurements are more representative of determining RF absorber characteristics.
