Rapid warming of cryopreserved biological tissues in a single-mode microwave resonance cavity

A 3-D numerical model has been developed to simulate warming process of the cryopreserved tissues in a single-mode (TE₂₁₀) microwave cavity. Using ice as a model tissue sample, the effect of sample volume and microwave power on the temporal and spatial temperature distribution as well as warming rates were investigated. The results show that rapid and uniform warming can be achieved. With an increase of microwave power, average warming rate increases linearly without changing uniformity of the heating
