Abstract
The purpose of this presentation is to formalize the full mathematical background of time-modulated linear arrays (TMLAs), in particular to determine the total losses due to their sideband radiation, once the time-modulation of their elements has been specified. Two modulation shapes (rectangular and trapezoidal pulses) and their corresponding power losses -given in closed form-, are considered and compared. The presented results allow evaluation of their advantages and drawbacks, thus leading to the optimal design of the time-modulation configuration.
