Abstract:The direct problem of exciting a multilayered spherical medium by a distribution of arbitrarily located (internal and external)
electric dipoles is considered. A formulation based on excitation operators is adopted. The solution of the direct problem is obtained by means of an overall superposition method that combines elements of the T‐matrix approach, the Sommerfeld's method, and Green's functions' techniques. Approximations are extracted for the obtained far‐field patterns in the long‐wavelength (low‐freq… Show more
