Electromagnetic scattering from a coaxial dielectric circular cylinder loading a semicircular gap in a ground plane

Gaussian Beam Scattering from a Semicircular Channel in a Conducting Plane

“…Figure 2 shows the backscattering width W b versus incident angle φ 0 with ka = 4π . An excellent agreement is achieved between the results in this paper and their correspondences in [5]. As mentioned above, the infinite series involved in the solution must be truncated after a certain number of terms, under the prerequisite of achieving the solution convergence.…”

“…The problem of plane wave scattering from a semicircular channel or the one loaded by a single or multilayer concentric dielectric circular cylinder as well as a dielectric coated conducting cylinder in a conducting plane has been studied extensively by Sachdeva and Hurd [1], Hinders and Yaghjian [2], Park et al [3,4], and Ragheb [5]. However, for some practical electromagnetic scattering problems, the effect of the incident wave shape sometimes becomes significant, depending on the antenna type, the target size, and the distance between the antenna and the target.…”

A Novel Coupled T-Matrix and Microwave Network Approach for Multiple Scattering From Parallel Semicircular Channels With Eccentric Cylindrical Inclusions

“…The channels, grooves and cracks in a ground plane have interesting electromagnetic scattering properties with applications in radar crosssection reduction and control, and thus have attracted extensive studies [1][2][3][4][5][6][7]. M. K. Hinders and A. D. Yaghjian provided exact dual-series eigenfunction solutions to a single semicircular channel [3] and the author of [5] extended the method to a semicircular channel with a coaxial circular cylinder inclusion.…”

“…M. K. Hinders and A. D. Yaghjian provided exact dual-series eigenfunction solutions to a single semicircular channel [3] and the author of [5] extended the method to a semicircular channel with a coaxial circular cylinder inclusion. A similar method is adopted in [6,7] for analysis of semielliptic channels using Mathieu function instead of cylindrical harmonics.…”

Electromagnetic plane-wave scattering from a sectorial groove in a perfectly conducting plane

“…[12]). In a few canonical cases, such as a semicircular trough [13][14][15][16][17], a shallow circular gap [18,19] and a semi-elliptic channel [20], the series approach based on the boundary value solution has been the commonly adopted technique. However, in most cases, even with simple geometry, the explicit analytical solutions are precluded.…”
