The properties of transient waves along electrical transmission lines are investigated. In particular, the excitation of the waves by impressed voltage and electric current sources is studied. Specific choices of this excitation are shown to lead to 'one-sided transmission' only. ...
A full analytic time-domain analysis is presented for a canonical problem of electromagnetic interference related to the operation of integrated-circuit devices at optical frequencies, where metal screens and substrates can no longer be characterized as perfect electrical conduct ...
Signal integrity in the far-field radiation from pulse-train excited array antennas is studied via full timedomain instruments. The disturbance in the received signal is related to the fidelity factor. At any point in our analysis, the disturbance is evaluated based on a reduced, ...
A full time-domain analysis is presented of the radiation properties of array antennas composed of identical, mutually translationally shifted, pulsed electric-current excited elements. An expression is derived for the radiated field in the farfield region, the parameters in whic ...
Analytic time domain expressions are derived for the pulsed electromagnetic field radiated by a narrow slot antenna with a dielectric layer in a two-dimensional model configuration. In any finite time window of observation, exact pulse shapes for the propagated, reflected, and re ...
