摘要：

Frequency-domain numerical modeling is performed and disc-shaped wide-aperture absorbing loads of calorimeters with a working liquid based on ethyl alcohol, which are designed to measure the energy of highpower microwave pulses, are optimized using the finite element method and the Nelder-Mead gradientless procedure. The possibility of using caprolon and polycarbonate as a load casing material with a corrugated inlet window together with low-pressure high-density polyethylene is investigated. The results of calculations significantly refined the results obtained earlier using a computational technique based on the finite-difference time-domain method for a simplified model of the absorbing load.
