The approximation of a hnction by a sum of complex exponentials is a problem that is at least two centuries old. Fundamentally, all techniques discussed in this article proceed from using the sameâ€¦ (More)

In this work, we propose a numerical method to obtain an unconditionally stable solution for the finite-difference time-domain (FDTD) method for the TE case. This new method does not utilize theâ€¦ (More)

We review several algorithms for estimating generalized eigenvalues ((;Eâ€™s) of singular matrix pencils perturbed by noise. The singular value decomposition ISVD) is explored as the common structureâ€¦ (More)

This paper investigates the effects of mutual coupling between the elements of an array on direct data domain algorithms. Mutual coupling severely undermines the interference suppression capabilitiesâ€¦ (More)

This paper proposes an alternative technique for adaptive spectral estimation. The new technique applies the method of conjugate gradient, which is used for iteratively finding the generalizedâ€¦ (More)

This paper focuses on the measurement of antenna radiation patterns when fully anechoic conditions are not available and, as consequence, some undesirable echoes are initially present in the measure.â€¦ (More)
