“…The analytical expressions are convenient for all coupled rectangular coaxial couplers having square inner conductors with a wide range of cut depths and an outer to inner conductor ratio between 1.4 and 10. We proposed others analytical expressions in order to calculate the EM parameters of squared coaxial lines [16]. All our analytical expressions were deduced from rigorous analyses by the FEM and MoM methods under respecttively FreeFEM and LINPAR [17] environments.…”

Using the finite element method (FEM) in two dimensions and the CST MICROWAVE STUDIO<sup>®</sup> (CST MWS) Transient Solver, the electromagnetic (EM) analysis and the design of a novel compact ultra wideband (UWB) bandpass filter using rectangular coaxial cables with square inner conductors, convenient for high power applications, are presented. The design of the UWB BP filter is based on the use of impedance steps and coupled-line sections. The center frequency around 6.85 GHz was selected, the bandwidth is between 3-10 GHz, the insertion-loss amounts to around 0.35 dB and the return loss is found higher than 10 dB in a large frequency range (4-9.5) GHz. The simulated results of stopband performances are better than 15 dB for a frequency range up to 11 GHz. For the selected center frequency and on a substrate with a dielectric constant of 2.03, the rectangular coaxial cables BPF with square inner conductors is only 6.7 × 8.9 × 33.4 mm in size

“…Because of this reason, other methods are used for calculation of the characteristic impedance of such perturbed conformal coaxial lines. The quasianalytical multipole theory method is presented in for analysis of a rectangular transmission line. In , the parameters of the square coaxial lines with a circular and a square inner conductor are investigated using the finite element method, method of moments, and curves fitting techniques.…”

The mathematically rigorous solution of the two‐dimensional Laplace equation for the multiple‐body systems is applied for accurate impedance calculations of transmission lines of arbitrary cross‐sections. The developed algorithm allows fast and accurate computations of impedance values for various positions of the inner conductor in the infinitely long transmission line. © 2014 Wiley Periodicals, Inc.
