Highly-Reconfigurable Time-based Radiating Systems and Their Optimization

This work aims at underlying the high reconfiguration capability of time-modulated arrays (TMAs) and their potential use in future 5G networks, as well as at stressing the need for a rigorous design tool when the optimization of these arrays is performed. The architectural simplicity of TMAs offers, as a counterpart, a complex dynamic radiating mechanism whose accurate description can significantly impact on the optimum solution. For this reason, a review of the available simulation strategies of TMAs is provided, mainly focusing on a recently proposed tool able to take into account all the dynamic linear and nonlinear phenomena occurring during a time-based radiation.
