Analytic descriptions of the fields of pulsed, finite-sized antennas are only approximate. For a review, see [1]. In general, numerical simulations are required for detailed characterization of the fields of pulsed antennas. See, for example, [2, 3, 4, 5, 6]. Here, we note that an “exact” form can be given for the fields in both the near and far zones of a pulsed dipole antenna in the limit tha...

An ac dipole with horizontally oriented oscillating magnetic field (spin flipper) was installed in RHIC to reverse the spin direction in the presence of two full Siberian snakes, thereby reducing the systematic errors for the spin physics experiments in RHIC. With two full snakes, the spin vector completes one full precession around the vertical direction in two revolutions, and the spin depola...

Under physiological conditions, supramolecular biological structures undergo nanoscale mechanical vibrations. Since proteins, which form building units of these structures, are usually highly electrically polar, mechanical oscillations will be accompanied by oscillating electric field. However, molecular modeling methods are not yet able to perform all-atom mechanical simulation of larger struc...

We present a new approach for analyzing band structures in one-dimensional Kerr-nonlinear photonic crystals. It combines the finite-difference time-domain method, based on the numerical simulation of oscillating dipole radiation, with the Kerr-nonlinear model. The approach is applied to analyze the band structures in Kerr-nonlinear one-dimensional photonic crystals as a function of the intensit...

We study a two-dimensional spin-orbit-coupled dipolar Bose-Einstein condensate with repulsive contact interactions by both the variational method and the imaginary-time evolution of the Gross-Pitaevskii equation. The dipoles are completely polarized along one direction in the two-dimensional plane to provide an effective attractive dipole-dipole interaction. We find two types of solitons as the...

Dipolar truncation prevents accurate measurement of long-range internuclear distances between nuclei of the same spin species, e.g., within (13)C-(13)C spin pairs in uniformly (13)C-isotope-labeled proteins, using magic-angle spinning solid-state NMR spectroscopy. Accordingly, one of the richest sources of accurate structure information is at present not exploited fully, leaving the bulk part o...

The voltage source maintains oscillatory voltage V0 e iωt between its terminals, which are also the ends of the two linear conductors of radius a and total length h. The voltage source can deliver whatever current I0 is required to maintain electric field E0 in the gap of length d, where V0 = E0d. The voltage source, including its terminals, is a small electric dipole oscillator with moment p0 ...

We investigate the impact of rotational diffusion on the electrodynamic coupling of fluorescent dye molecules (oscillating electric dipoles) to a tunable planar metallic nanocavity. Fast rotational diffusion of the molecules leads to a rapidly fluctuating mode density of the electromagnetic field along the molecules' dipole axis, which significantly changes their coupling to the field as compar...
