A new technique for the quasi-TEM analysis of conductor-backed coplanar waveguide structures

Synthesis formulas for conductor‐backed coplanar waveguide

“…Many papers have been reported to determine the characteristic impedances and effective dielectric permittivities of various conductor-backed CPWs [3][4][5][6][7]. All of these papers deal with the quasi-static analysis of conductor-backed CPWs.…”

Neural models for the V‐shaped conductor‐backed coplanar waveguides

“…In [6], analytical formulas for the quasi-TEM parameters of CPW obtained from either exact or approximate CMM were proposed allowing for the presence of upper shielding, conductor backing, and finite-extent lateral ground planes. The numerical formulas based on SDA were presented in [7] for the analysis of the quasi-TEM parameters of CBCPW structures. A direct method of calculating the electromagnetic field patterns surrounding the CBCPW was proposed by Gillick et al [8].…”

Accurate Synthesis Formulas Obtained by Using a Differential Evolution Algorithm for Conductor-Backed Coplanar Waveguides

“…Various types of CBCPW structures have been presented and analyzed in the literature [4][5][6][7][8][9][10][11]. The CBCPWs were analyzed by using the spectral domain approach (SDA) [4], conformal mapping method (CMM) [5,6], and quasi-static SDA [7].…”

“…The CBCPWs were analyzed by using the spectral domain approach (SDA) [4], conformal mapping method (CMM) [5,6], and quasi-static SDA [7]. The dispersion characteristics of CBCPWs have been obtained by using the rigorous mode matching method [8], alternative formulation of the transverse resonance technique [9], full-wave SDA and Galerkin's method [10], and a hybrid two-dimensional finite-difference time-domain/Marquardt curve-fitting technique [11].…”

“…Among these advantages, CBCPWs allow easy implementation of mixed coplanar/microstrip circuits, reduce radiation effects, and raise effective permittivity. These and several other advantages make CBCPWs ideally suit for MIC as well as monolithic MIC (MMIC) applications [1][2][3][4][5][6][7][8][9][10][11][12].…”
