Dielectric properties of rat nasal tissue and nasal carcinoma is given in this work between 500 MHz to 6 GHz. Nasal carcinoma is induced by oral administration of single dose 20 7,12-Dimethylbenz[a]anthracene (DMBA) dissolved in 1 ml olive oil to 47 days old Sprague Dawley (SD) rats. A granular tissue anomaly in one rat along with bleeding is observed after 15 weeks from the administration of the carcinogenic agent. In-vivo dielectric properties are collected both from the granular nasal carcinoma tissue and healthy counterpart with open-ended coaxial probe technique. A median dielectric property discrepancy is observed in the whole frequency range between the nasal carcinoma and healthy tissues.
