Distributions of Electric and Thermal Fields in a Rectangular Microwave Chamber with a Cylindrical Phantom

Microwave Rewarming of Limb Frostbite Injuries (Simulation of Modes)

“…As noted above, because a human limb does not lend itself easily to a mathematical description, initially, the modeling was performed by imitating it with a dielectric phantom of a more basic shape with similar dielectric permittivity and thermal conductivity. For example, the paper [29] explores field distributions in a cylindrical dielectric phantom inside a microwave chamber (Figure 9).…”

“…Practically at the same time as we were trying to describe this process with mathematical models, attempts were being made to perform physical modeling of the frostbite rewarming process in dielectric phantoms imitating a human limb. Initially, it was a thin wall polymer cylinder filled with normal saline [29]. Afterwards, arm [30,31] and leg [32] phantoms were created (Figure 12).…”

“…The frequency dependence of the voltage standing wave ratio, the dotted line corresponds to a single-layer phantom, the solid line to a two-layer phantom [29]. for temperature distribution in the volume of a cylindric phantom (Figure 12a) filled with ground pork meat.…”
