Explicit Derivation

A simple and explicit derivation for the vertical electric dipole excited by a short-pulse current and located above a layered dielectric medium is derived in an analytical form using the Cagniard–de Hoop method. The fields are expressed as the convolution of the exciting current with the layered medium response. This response is obtained directly from the integral representation for the magnetic fields in the frequency domain and is expressed as a finite integral. A modified Cagniard method is then used to derive closed-form expressions for the vertical dipole anywhere above a multilayered medium. The method is used to perform numerical calculations of the magnetic fields for applications to geo-radar operating on layered media. PACS Nos.: 41.20.Jb, 42.25.Bs, 42.25.Gy
