Numerical simulation of pressure waves in the cochlea induced by a microwave pulse

摘要: The pressure waves developing at the cochlea by irradiation of body with a plane wave microwave pulse are obtained numerical simulation, employing two-step finite-difference time-domain (FDTD) algorithm. First, specific absorption rate (SAR) distribution is solving Maxwell equations on FDTD grid. Second, temperature rise due to this SAR used formulate thermoelastic motion, which discretized and solved method. calculations performed for anatomically based full human models, as well head model. dependence amplitude frequency, direction propagation, polarization incident electromagnetic radiation, width, was investigated.
