Eigenvalue contour lines of Kac-Murdock-Szego matrices with a complex parameter
George Fikioris, Christos Papapanos
A previous paper studied the so-called borderline curves of the Kac--Murdock--Szegő matrix , where . These are the leve…
Eigenvalue bifurcations in Kac-Murdock-Szego matrices with a complex parameter
George Fikioris
For complex , the spectral properties of the Toeplitz matrix , often called the Kac-Murdock-Szegο matrix, have been examined in deta…
Alleviating Oscillatory Approximate-Kernel Solutions for Cylindrical Antennas Embedded in a Conducting Medium: a Numerical and Asymptotic Study
Th. K. Mavrogordatos, C. Mystilidis, P. J. Papakanellos +1
We alleviate the unnatural oscillations occurring in the current distribution along a linear cylindrical antenna center-driven by a delta-function generator and embedded in a condu…
On the Application of Numerical Methods to Hallen's Equation: The Case of a Lossy Medium
Christos Mystilidis, Panagiotis J. Papakanellos, George Fikioris +1
A previous paper analyzed in detail the difficulties associated with the application of numerical methods to Hallen's integral equation with the approximate kernel for the case of…
An Effective-Current Approach for Hallén's Equation in Center-Fed Dipole Antennas with Finite Conductivity
Themistoklis K. Mavrogordatos, Anastasios Papathanasopoulos, George Fikioris
We propose a remedy for the unphysical oscillations arising in the current distribution of carbon nanotube and imperfectly conducting antennas center-driven by a delta-function gen…
On the asymptotics of a cotangent sum related to the Estermann zeta function
George Fikioris
The sum is related to the Estermann zeta function. A recent paper computes the first two terms of the large- asymptotic expansion of…
