Textbook Question
Chapter 11, Problem 11.8P
An electric field in free space is given in spherical coordinates as Es(r) = E0(r)e-Jkra^V/m. (a) Find Hs.(r) assuming uniform plane wave behavior. (b) Find < S >. (c) Express the average outward power in watts through a closed spherical shell of radius r, centered at the origin, (d) Establish the required functional form of Er,(f) that will enable the power flow in part c to be independent of radius. With this condition met: the given field becomes that of an isotropic radiator in a lossless medium (radiating equal power density in all directions).
