Data of Dielectric Measurements - Trachea

This page contains relative complex permittivity and electric conductivity at the corresponding frequencies measured by the Laboratory. Dielectric measurements were performed using the measurement techniques of [5][8][9][10], with tissue samples of animal by-products in almost all cases at tissue temperatures around body temperature (30 oC–37 oC).

CSV files of the measured data for each tissue can be downloaded here. Select any tissue from the following to view a list and figures of its dielectric properties. The figure also shows reference measurement data, if available. The source of the reference data is [4] (see also [2]), except for dermis and epidermis [6].
