Image charge inclusion in the dielectric sphere revisited [PDF]

open access: yes, 2012
Van Siclen (1988 Am. J. Phys. 56 1142) reported a curious property of a dielectric sphere in the field of an external point charge: the field outside the sphere generated by the combination of the original charge exterior and the Kelvin image charge ...

An extension of the Kelvin image theory to the conducting heaviside ellipsoid [PDF]

open access: yes, 2011
The Kelvin image theory for a conducting sphere is extended to the case of a conducting oblate spheroid in uniform motion along its axis of revolution (a Heaviside ellipsoid) using the well-known method provided by Special Relativity.

Newtonian Gravitational Potential For An Oblate Spheroid [PDF]

open access: yes, 1962
By considering a boundary value problem of Laplace\u27s differential equation, we construct a gravitational potential function for an oblate spheroid using Newton\u27s law of universal gravitation.

Shape effect of Co nanoparticles on the electric and magnetic properties of Co–SiO2 nanogranular films

open access: yesAIP Advances, 2022
Controlling the magnetic anisotropy of nanoparticles is a crucial but challenging step for developing new magnetic functions. Here, we demonstrate a simple approach to controlling the shape of Co nanoparticles in a Co-SiO2 nanogranular film from oblate ...

A New Modified Helmholtz Equation for the Expression of the Gravity Gradient and the Intensity of an Electrostatic Field in Spherical Harmonics

open access: yesMathematics, 2023
In this work, it is shown that the geometry of a gravity field generated by a spheroid with low eccentricity can be described with the help of a newly modified Helmholtz equation.

An Efficient Computational Technique for the Electromagnetic Scattering by Prolate Spheroids

open access: yesMathematics, 2022
In this paper we present an efficient Matlab computation of a 3-D electromagnetic scattering problem, in which a plane wave impinges with a generic inclination onto a conducting ellipsoid of revolution.

The forward problem of magnetometry for the oblate spheroid

open access: yesContributions to Geophysics and Geodesy, 2011
We present analytical solution of the forward magnetometric problem for the oblate spheroid (rotational ellipsoid) as a causative body. The shorter semiaxis of the ellipsoid is supposed to be vertical to the surface of the earth.

AXISYMMETRIC DYNAMIC BEHAVIOUR OF THIN OBLATE SHELLS

open access: yesJournal of Engineering
This paper presents a theoretical investigation of the axisymmetric free vibrations of an isotropic thin oblate spheroid shell. The analysis depends on the Rayliegh – Ritz's method. The non – shallow shell theory is used for the analysis.

Theoretical bases of the geometrical identification of a common inter-radar space [PDF]

open access: yesZbornik Radova: Geografski institut "Jovan Cvijić", 2013
A condition for the successful inter-radar comparison between two radars is the timespace synchronization in the middle region where the comparison is the most effective.

The Oblate

open access: yes, 2013
Towards the end of the nineteenth-century, the French writer Joris-Karl Huysmans — famous for his decadent novel A Rebours (1884) — became engaged in a process of religious conversion. This process was described in a series of novels, ending with L’Oblat
