Minimum Energy Requirement for Inducing Withdrawal Reflex in Millimeter Wave Exposures

We consider the problem of inducing withdrawal reflex on a test subject via exposure to millimeter wave beam. In our physical model, there are 10 parameters affecting occurrence reflex. Our goal is pinpoint roles these in first carry out non-dimensionalization reduce model non-dimensional system only 3 composite parameters: beam power density, radius, and time. If kept steady, occurs eventually; shortest time for corresponds smallest energy consumption at given density radius. 2D space overall minimum corner very large small which also produces value maximum skin temperature long To burn injury risk, we introduce cap temperature. At each total power, optimizations with respect constrained by prescribed cap. The varies negatively cap: lower can be accommodated higher venue larger relatively flat attains moderately power. approximately inversely proportional analysis demonstrates that good compromise achieve both low short
