PROJECT TITLE :

Representation of Electromagnetic Responses in Time Domain Using State-Space System Identification Method

ABSTRACT:

This paper presents a management system methodology based on system identification (SI) to derive state matrices and system dynamics for the extrapolation of simulated time-domain electromagnetic (EM) responses using each input and output data. The strategy is applied to model transient responses for a dielectric resonator and a wideband slot antenna computed by the finite-integration technique using non-Gaussian excitation pulses usually used in digital signals. Using state-space SI formulation, a compact illustration of the output time-domain signal comes, including the first-time transient responses, and its numerical implementation depicts no instability in late-time responses plotted well beyond the steady state. Furthermore, all the system poles are found to lie among the unit circle in the complicated plane. Wonderful model corroboration is achieved with independently computed frequency domain data or measured results using modest pc resources.
