Microwave assisted technologies and its application are widely used in different research fields. One of the main difficulty of this area is to design a treatment chamber. The aim of this paper is to measure power absorption and calculate average surface microwave power density of composite dielectric materials, based on plant particles. Obtained microwave-absorbing characteristics of composite plant material can be used in microwave assisted processes and high-performance microwave treatment chambers design to facilitate the research in microwave assisted drying and extraction. The research includes experiments with different positioning of the composite materials from reflective metal screen inside the chamber-waveguide.
