This letter discusses a microstrip line with an open-end termination in which the reflected microwaves can be optically controlled by a laser illumination. The frequency characteristics are emphasized rather than the time domain ones. The reflection characteristics have been demonstrated experimentally and theoretically for the frequency range of 24 GHz. In the theoretical treatment both the conductance and the capacitance are considered in the equivalent circuit model of the open end of the strip.
