Abstract

A model-guided design methodology for polymer composite electromagnetic (EM) interference shields is presented. The approach utilizes measurement of intrinsic complex EM parameters, predictive modeling of absorbing geometries in the COMSOL environment, and subsequent fabrication using 3D printing and compression molding. The viability of the first two steps in the approach was confirmed using a commercially available conductive nano-filled polymer composite filament, as well as a model system from the literature. Initial results suggest that the addition of periodically placed air-filled pores within the conductive polymer composite can lead to lower reflection loss and higher absorption bandwidths.
