Finite Temporal Support Pulses for em Excitation

A new family of pulses is introduced. It consists of a windowed-power (WP), unipolar prototype, a unicycle, and a pulse with almost rectangular spectral diagram. These pulses have finite temporal support, controlled continuity at onset and end, and are tailored via simple design rules. The WP prototype has a very low spectral leakage. The WP monocycle's effectiveness as excitation in computational schemes is demonstrated via numerical experiments. Its signature is also shown to practically overlap one generated by readily available circuitry. The WP pulses are opportune as excitation in electromagnetic analysis, for time-windowing purposes, and for feeding pulsed-field or timed antenna arrays.
