Analytic Analysis of Electromagnetic Fields in a Round Area

In order to analyze the effect of the different frequency on the distribution of electromagnetic field, this paper presents the theoretical research on bioelectrical impedance measuring technology in either quasi-static field or non-quasi-static field in a round area. The analytical equations are derived with the method of separation of variables. The comparative analysis of Matlab figures which show that as frequency changes, the equipotential line of the electromagnetic field distorts and there is a difference between the electric potential in the quasi-electromagnetic field and that in the non-quasi-electromagnetic field
