摘要：

Beta tricalcium phosphate (beta-TCP) bioceramics and chitosan biopolymers are used as biomedical implants because of their better biocompatibility and good bioresorption characteristics. As they are biomaterials, they have good interactions with microwave frequencies. beta-TCP and chitosan powder, films. pellets, and gel are prepared and studied at the S-band microwave frequencies. Dielectric parameters such as dielectric constant, dielectric loss, conductivity and S-parameters are evaluated. Dielectric parameters of different forms of beta-TCP and chitosan show resemblance with that of human tissues. Hence. these materials can also be considered as potential phantoms for specific absorption rate measurements as well as in microwave imaging applications. (C) 2009 Wiley Periodicals, Inc.
