Summary:
In vitro studies to investigate biological effect of electromagnetic field are performed for microwave to millimeter-wave frequency band. A reliable measurement method of complex permittivity for biological cells is required for the dosimetry. The feasibility of applying the waveguide penetration (WP) method to measure complex permittivity for cells in the frequency range from microwave to millimeter-wave frequency band is investigated. In this study, complex permittivity measurement was performed in the frequency ranges from 1.7 to 2.6 GHz and from 50 to 65 GHz by the WP method. Real part and imaginary part of complex permittivity of CHO-K1 cell were estimated to be 59.9-64.1 and 15.6-20.2 in the frequency ranges from 1.7 to 2.6 GHz, and 10.6-14.2 and 15.2-20.0 in the frequency ranges from 50 to 65 GHz, respectively.
