Adaptive beam forming in time-domain

This paper introduces a new technique for adaptive beam forming in time domain of an array of slot antennas with finite widths. The time dependent field is computed using the closed-form expressions for the radiated EM fields. The radiated energy is focused at a desired space and time and minimized in other regions to satisfy the requirements of a biomedicine hyperthermia. Setting of excitation properties of particular slots leads to optimization problem that is solved using a new stochastic multi-objective algorithm called MOSOMA (Multi-Objective Self-Organizing Migrating Algorithm).
