A simplified method for calculations of the current in a tunnelling junction with its orientation and spatial distribution is described. The current at test points on either electrode is calculated for the shortest distance with expressions for point

Point-contact metal–insulator–metal (MIM) diodes have been used for detection and mixing at frequencies as high as 520 THz. In detection, the current responsivity (CR), defined as the change in the DC current caused by an incremental change in th

This work presents a derivation of expressions for the electromagnetic fields propagating at a frequency near gyromagnetic resonance on a ferrite cylinder magnetized by an applied axial dc magnetic field. This system allows propagation by hybrid surf

When optical radiation is focused on a nanoscale field emitter tip, the potential and emitted current follows each cycle of the radiation field. Nonlinearity causes mixing of the optical radiation from two lasers so that current oscillations from dc

Solutions of the time-dependent Schrödinger equation show that the tunneling current in a field emitter may be modulated by means of a laser. The steady-state response is calculated with Floquet methods, and the transient response is determined with

The definition of the curl operator in terms of an integral is shown to lead to a method for numerical solutions that facilitates the use of mixtures of cells having different shapes and different dielectric properties. The derivation is followed by

Minimally perturbing, resistive, nonferrous probes were developed for noninvasively measuring hazardous currents induced in the human body by electromagnetic fields at 1-200 MHz. Each probe has a resistive toroidal coil that is placed around the leg
