We characterize the properties of oneand two-dimensional transmission lines periodically loaded with electronic switches, for use in managing amplitude and propagation orientations of pulses traveling on the lines. The detection of the input voltage level is successfully demonstrated experimentally using the test switch line. Moreover, the orientation of pulse propagation is controllable in a t...

Observations of the Southern Hemispheric winter conditions indicate that the major warming of September 2002 resulted from a combination of stationary wave-1 and traveling wave-2 forcing events and suggest that wave and mean-flow anomalies present earlier that winter may have also played a role. Quantities such as the location of the zero wind line, the strength and wave geometry of the vortex,...

Simultaneous ideal quantum measurements of multiple single-photon-level signals would advance applications in information processing, metrology, and astronomy, but require the first amplifier to be simultaneously broadband, limited, directional. However, conventional traveling-wave parametric amplifiers support broadband amplification at cost increased added noise are not genuinely directional ...

In this paper, we investigate the instability of one-dimensionally stable periodic traveling wave solutions of the generalized Korteweg-de Vries equation to long wavelength transverse perturbations in the generalized Zakharov-Kuznetsov equation in two space dimensions. By deriving appropriate asymptotic expansions of the periodic Evans function, we derive an index which yields sufficient condit...
