Thin and flexible multilayer polymer composite structures for effective control of microwave electromagnetic absorption

The stacked multilayer structures are easy to make, modular, and open up new possibilities in the area of microwave management (broadband shielding by absorption or frequency-selective filtering, also called bandgap control). The analytical model developed to simulate the absorbers and filters is in good agreement with experimental characterisation and could be further extended to the design of systems operating in other frequency ranges.
