The Physical Reality of Space and Surface Waves in the Radiation Field of Radio Antennas* By
Evidence is presented which indicates that, notwithstanding the change in sign made by Sommerfeld in his 1926 paper on radio wave propagation, the radiation field of a vertical electric dipole may be separated into space and surface wave components. Sommerfeld's original concepts as to the characteristics of two such waves in radio transmission are largely substantiated. It is shown that a spac...
متن کاملExact Transient Field of a Horizontal Electric Dipole Excited by a Gaussian Pulse on the Surface of One-dimensionally Anisotropic Medium
In this paper, the propagation model considers the two half-spaces as a homogeneous isotropic medium and one-dimensionally anisotropic medium. From the exact formulas for the transient field with delta-function excitation, it is obtained readily the exact formulas for the transient field excited by a horizontal electric dipole with Gaussian excitation when both the dipole point and field point ...
متن کاملAuxiliary Potentials In Chiral Media
In the present paper, the expressions for scalar and vector potentials in lossless isotropic chiral media are analyzed. Propagating eigenvalues of these potentials are then obtained. Furthermore by decomposition of sources and fields in a chiral medium, we introduce the auxiliary right-and left-handed potentials and find the associated fields. These potentials are used to solve the problem of a...
متن کاملCortical Dipole Layer Imaging of Brain Electrical Activity in Horizontal and Sagittal Planes
Horizontal and sagittal dipole layer distributions were estimated from scalp electroencephalogram for three dimensional dipole imaging of brain electrical activity. Horizontal dipole layer being parallel to the brain surface has been used in previous head models. In the present study, the dipole layer distribution in the sagittal plane was also introduced to identify the position of dipole sour...
متن کامل0 Laser Excitation of Polarization Waves in a Frozen Gas
Laser experiments with optically excited frozen gases entail the excitation of polarization waves. In a continuum approximation the waves are dispersionless, but their frequency depends on the direction of the propagation vector. An outline is given of the theory of transient phenomena that involve the excitation of these waves by a resonant dipole-dipole transfer process.
