在微波至毫米波频段进行了电磁场生物效应的体外研究。剂量学需要一种可靠的生物细胞复介电常数测量方法。研究了波导穿透法在微波至毫米波频段测量细胞复介电常数的可行性。在本研究中，采用WP方法在1.7 ~ 2.6 GHz和50 ~ 65 GHz频率范围内进行了复介电常数测量。在1.7 ~ 2.6 GHz频率范围内，CHO-K1电池复介电常数实部和虚部分别为59.9 ~ 64.1和15.6 ~ 20.2，在50 ~ 65 GHz频率范围内，复介电常数实部和虚部分别为10.6 ~ 14.2和15.2 ~ 20.0。
In vitro studies to investigate biological effect of electromagnetic field are performed for microwave to millimeterwave 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.
