Dynamics of oscillating pulse edges in two-dimensional switch lines

The oscillating motions of a wavefront on a twodimensional (2D) switch line, i.e., a transmission line periodically loaded with electronic switches (the switch is open for voltages greater than a fixed threshold and closed otherwise), are discussed. In a twodimensional switch line, the amplitude of the wavefront decays more rapidly than in a one-dimensional switch line, and the oscillation frequency depends on the propagation orientation. The rapid decay of the wavefront, supported by inherent frequency entrainment, is useful for generating high-frequency voltage waves.
