Abstract

Many time-domain electromagnetic measurements require sensors that generate accurate signals proportional to the incident electric field for some finite clear time, after which the response may be of little interest, except for a possible frequency-domain requirement on the damping of resonances. In a review of earlier work,1 examples of such devices are given that combine more conventional antennas with open transmission lines. In designs that can have highly directional properties, antenna effective height h eff, risetime t r , and clear time t c may be chosen independently. Current work focuses on extending the parameter range of these sensors to greater sensitivity and shorter risetimes, where sensor performance becomes limited by the effects of skin and dielectric loss and dispersion. These limitations are largely overcome through the use of guided-wave optics in sensor designs.
