I have these equations in my book, but I don't know how I can use them in this problem Electric field of a plane has surface electric density σ: E = σ/2εε₀...
In the graph above, it shows a uniform charged ring of radiusaand chargeQin the z = 0 plane and centered at the origin (just to make things easier). The distance from an eleement of chargedqto the field pointPon the axis of the ring isr=z2+a2. Now substituing the given values in...
A jellium/free-electron model is used to estimate the static electric field at the surface of a metal cluster. The electric field near a cluster with a radius of 10鈥 50 au is found to deviate significantly from the field at the same distance from an infinite metallic plane. This will ...
This impedance anomaly is traced back to a generalized resonance condition reminiscent of Harper’s equation for electronic lattice transport in a magnetic field, even though our circuit network does not involve magnetic translation symmetry. It exhibits an emergent fractal parametric structure of ...
Here, we fix a process with an invariant field, and study the fluctuations of the flux through large arcs and curves in the plane. Under suitable conditions on the process and on the curve, denoted \Gamma , we show that the asymptotic variance of the flux through R\,\Gamma grows like ...
The Hamiltonian for the electric-dipole energy, induced by an external electric field , is written as The Hamiltonian for the Zeeman energy of an electron, under an in-plane magnetic field B(t), is given by where ge is the Landé factor, μB is the Bohr magneton, and B(t) = B...
We analyze the dynamic toroidal multipoles and prove that they do not have an independent physical meaning with respect to their interaction with electromagnetic waves. We analytically show how the split into electric and toroidal parts causes the appearance of non-radiative components in each of the...

function that, when convolved with a time series recording geomagnetic variation, gives an estimate of the geoelectric field that is time-causal, a quality of importance for real-time operational algorithms. Love and Swidinsky (2014) used a simple four-parameter model of lithospheric conductivity:...
