Scattering of Electromagnetic Waves from a Deeply Buried Circular Cylinder

Scattering from a Cylindrical Object Buried in a Geometry with Parallel Plane Interfaces

“…Consider now far-zone scattered field expression in the region III of dielectric half-space geometry [4].…”

“…T 12 is Fresnel transmission coefficient. First consider the field expression in region I of this geometry [4].…”

“…Far-zone scattered field from a circular cylinder deeply buried in the grounded dielectric layer is [4] …”

“…From this comparison corresponding factors in each term will be identified. The dominant term of radiated field G 1 (ρ, φ; ρ , φ ) in region I is given as [4] …”

“…One assumption is that object is far away from interfaces containing the object. In such situations, interaction terms may be evaluated using an asymptotic approximation for large separation of the object from the interfaces [1][2][3][4][5] and the analysis becomes relatively simple. Even with above assumption and approximation, situation remains complicated if number of interfaces are increased.…”
