《物理电学》英文版教学课件Electric Field of a Dipole.ppt,An electric dipole consists of two charges of the same magnitude q, but opposite sign, separated by a distance L. If the dipole is molecular, it could be an induced dipole created by external charg
The electromagnetic fields of a horizontal electric dipole buried in a medium covering one-dimensionally anisotropic medium are studied. There are three media, one-dimensionally anisotropic medium covered with a dielectric under the air. The electromagnetic field components are complex because of the ...
The equation for the electric field of a dipole is E = k(q/r^3)(2cosθ), where k is the Coulomb constant, q is the magnitude of the charge, r is the distance between the charges, and θ is the angle between the line connecting the charges and the point in space where the ele...
We obtain and analyze a solution of the boundary-value problem for the field of an electric dipole centered in a vacuum cavity inside a small plasma spheroid. The influence of the cavity size on the field enhancement in an outer vacuum region is analyzed as a function of the curvature of ...

The field of a point electric dipole in an infinite dielectric is obtained by placing the dipole at the center of a spherical cavity of radius R inside the dielectric and then letting R→0. The result disagrees with the elementary answer found in textbooks. The mathematical and physical reasons...
