Abstract

AbstractIn this article, the electromagnetic surface waves propagating along an interface between two dielectric media or an interface between air and a multilayered structure in planar, cylindrical, and spherical geometries are introduced. Specific surface waves considered are (1) the Zenneck surface wave, (2) the surface wave on a conductor‐backed dielectric slab, (3) the radial cylindrical surface wave on a flat surface, (4) the axial cylindrical surface wave, (5) the surface wave on a dielectric‐coated conducting cylindrical, (6) Norton and trapped surface waves on flat ground interface, (7) surface‐wave propagation over an inhomogeneous flat surface, and (8) surface‐wave propagation over a spherical ground. Several examples are given to illustrate the propagation of surface waves in these geometric structures. The surface waves propagating along Earth's surface have been used for wireless communications and remote sensing. On the other hand, the surface waves on conductor‐backed dielectric slabs become a problem in microwave printed circuits and microstrip antenna systems. The understanding and control of surface waves are therefore important in radio systems.
