Higher-order modes for broadside-coupled striplines in a shield

Abstract

[1] A mode-matching method is applied to broadside-coupled striplines in a shield to obtain a dispersion relation. Higher-order mode analyses are performed, and their cutoff frequencies are evaluated. Good agreement with existing solutions is demonstrated. Higher-order field characteristics are illustrated. The mode-matching model provides an efficient and stable means of analyzing broadside-coupled striplines in a shield.Citation: Eom, H. J., J. J. Kim, and J. S.

Electrostatic Solution for Broadside-Coupled Striplines in a Shield

“…The CTL cells consist of uniform and tapered sections. Higher-order TE and TM wave propagation along the uniform section was studied in [4]. Higher-order modes for offset striplines in a shield were studied in [5].…”

“…While Helmholtz's equation was used in [5] for higher-order mode analysis, Laplace's equation will be used here for the TEM wave analysis. The purpose of this letter is to solve Laplace's equation for broadside-coupled striplines in a shield using the mode-matching method [4], [5]. The analysis follows next.…”
