This work analyzes (and looks to control) the manifestations of loss in polymer composites in the THz spectrum due to material crystallinity, material charge carrier densities, and suboptimal fabrication. Polymer composites are fabricated from a variety of materials and their losses are characterized using THz time-domain spectroscopy. It is found that reduced crystallinity, large free carrier densities, and suboptimal fabrication can lead to significant losses. Nonetheless, such losses can be mitigated with appropriate selection of the inclusion and host materials and careful processing of the resulting composite.
