Microwave method for determing dielectric parameters of living biological objects I.

At frequencies higher than 3 GHZ the dielectric constant and dielectric loss of the proteins and of water bound to them are negligible as compared to dielectric values of water. Therefore microwave measurements give direct information of dielectric properties of water contained in living cells (Schwan, 1965). In our work we have developed a method for determining microwave dielectric parameters of biological objects and carried out exploratory measurements at 6.3 GHZ, in temperature range 20-50 degrees C.
