https://doi.org/10.1057/9780230598317Although spherical harmonics will not appear explicitly in the sequel, it seems impossible to write a textbook on the subject of electromagnetic theory without a brief account of some of their most fundamental features.

The Skullcap, Cranial Vault or Calvarium,Throughout the remainder of the book we shall be primarily concerned with fields possessing a simple harmonic time dependence. Since the time dependence of all fields and currents must be the same, it is useful to suppress the common time factor with the aid of complex notation. We shall write the real quantity .(.) as

Steven M. Sperry,Nitin A. PagedarTo illustrate the general waveguide theory thus far developed, we shall determine the mode functions and associated eigenvalues for those few guide shapes that permit exact analytical treatment. In this chapter we will discuss guides constructed from plane surfaces. Circular boundaries will be the subject of Chap. 8.

Taranjit Singh Tatla,Elena Boyd,Hassan HirjiWaveguides with cross-sectional boundaries composed wholly, or in part, of circular arcs are most conveniently discussed with the aid of polar coordinates . and φ,

Jeyasakthy Saniasiaya,Norhafiza Mat LazimIn this chapter we take a brief digression to illustrate a familiar application of the mode decomposition discussed in Chap. 6. The notions discussed here will be significantly generalized in Chap. 13, when junctions between waveguides will be considered.

Dieter Hofmann,Gabriele BergertThe wave nature of light is manifested by diffraction. Such problems are notoriously diffcult to solve. Here we indicate two approaches – the first, based on a variational principle, and the second, valid for short wavelengths, based on the exact solution found by Sommerfeld in 1896 for the diffraction by a straight edge.
