Induced toroid structures and toroid polarizabilities

Physical Review D, 1987
The frequency-dependent toroid dipole polarizability ..gamma..(..omega..) of a (nonrelativistic, spinless) hydrogenlike atom in its ground state is calculated analytically in terms of two Gauss hypergeometric functions. The static result reads ..gamma..(..omega.. = 0) = (23/60)..cap alpha../sup 2/Z/sup -4/a/sub 0/ /sup 5/(..cap alpha.. = fine-structure

A Toroidal Magnetron

Proceedings of the Physical Society. Section B, 1950
A rearrangement of the geometry of cavity magnetron oscillators is proposed such that the magnetic field loops around the cathode, whereas waves and electrons travel along it. Application of various magnetron theories to the new geometry leads to the result that the device will oscillate under conditions similar to those for a conventional cavity ...

Toroidal runaway beams

Physical Review E, 2013
We investigate the dynamics of a special group of runaway electrons which possibly play an important role in toroidal fusion devices. Starting from the torus center they are accelerated by a toroidal electric field and are hence forced to move across the toroidal magnetic field into regions with rising poloidal field in order to compensate for the ...

ON TOROIDAL FUNCTIONS

Canadian Journal of Physics, 1959
The general solutions of Laplace's equation in toroidal co-ordinates have been derived, both for the three-dimensional and the axial symmetrical cases. Also, the general theory and properties of toroidal functions have been briefly outlined.The numerical tables for the zonal and the tesseral toroidal functions were calculated by the I.B.M.

Toroidal Microphones

The Journal of the Acoustical Society of America, 1969
“Toroidal” microphones are defined as microphones having toroid-shaped directional characteristics, i.e., they have minimum sensitivity along the rotational axis of the toroid and maximum sensitivity in the plane perpendicular to that axis. Several practical designs of toroidal microphones based on second-order gradient receivers are proposed and ...

Axisymmetric Toroidal Equilibrium with Sheared Toroidal Flows

Plasma Science and Technology, 2002
Problem of the axisymmetric toroidal equilibrium with pure sheared toroidal flow is involved. For standard tokamak equilibrium, general approximate solutions are analytically pursued for arbitrary current profile and non-circular cross-section. Equilibrium properties including the flow-induced density asymmetry are analyzed.

Toroidal networks

IEEE Communications Magazine, 1988
The essential features of the toroidal network topology are examined, and its performance is evaluated. Some of the proposed applications of toroidal networks are described. Included in the discussion are metropolitan area network communication and multiprocessor interconnection, as well as the use of VLSI technology. >

Toroidia toroides

2019
Toroidia toroides (Hoffman, van Heugten & Lavaleye, 2011) (Fig. 7A) MATERIAL EXAMINED. — 18 sh., DW130. REMARKS This is the first report of this species after its original description from off NW Morocco in 529 m. It was diagnosed by the occurrence of a spiral sculpture whereas the interspaces between ribs are smooth in the similar Margarites laminarum
