Broadside-coupled striplines in a shield are basic guiding structures in coupled transmission line (CTL) cells that are important in EMI/EMC applications [1]–[3]. The CTL cells exhibit good performance in terms of field uniformity and bandwidth. 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-ord...
