Comments, with reply, on "Deterministic approach to full-wave analysis of discontinuities in MICs using the method of lines" by Z. Chen and B. Gao

The commenters points out that in the above-titled paper by Z.-Q. Chen and B.-X. Gao (see ibid., vol. 37, p. 606-611, 1989) equations (16) and (17) can not be derived from expressions (6) to (15). The authors concur with the commenters, but maintain that expressions (7) and (8) are correct. >

Full-wave analysis of discontinuities in conductor-backed coplanar waveguides using the method of lines

A three-dimensional analysis using the method of lines with nonequidistant discretization is described to investigate the discontinuities in shielded conductor-backed coplanar waveguides (CBCPW's). An extended approach concerning the treatment of the boundary conditions at the input and output ports is proposed in which the reflection and transmission coefficients can be directively obtained in a single calculation. The validity and convergence of the numerical results are checked and gaps with various shapes in CBCPW's are analyzed and compared. Finally, the frequency response of a simple step discontinuity is calculated as an application to nonsymmetrical structures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Deterministic approach to full-wave analysis of discontinuities in MICs using the method of lines

Arbitrarily shaped one-port and in-line two-port discontinuities in any quasiplanar configuration can be analyzed by this one-step method. Using the hybrid homogeneous conditions, this approach simplifies the calculation, with Psi /sup e/ and Psi /sup h/ being discretized only in and near the discontinuity regions. Illustrative examples of S-parameter calculation are given. Computed results are compared with measured data and with the published results of other authors. >
