HIFREQ can carry out such calculations for two different forms of externally applied fields: a constant (electrostatic) electric field or a general electromagnetic plane-wave. HIFREQ可以执行另种类型的外加场运算:连续的电场(静电场)或者是一般的电磁平面波。 ParaCrawl Corpus The absorption coefficient...
An electromagnetic wave from a wire antenna travels(from the reader)toward the plane of the paper. At timet=0.0sit strikes the paper at normal incidence. At point0andt=0.0s,the magnetic field vector has its maximum value,4.50×1...
2 Electromagnetic interference (EMI) shielding 2.1 General EMI shielding theory Electromagnetic shielding theory corresponds to a shielding of an electromagnetic plane wave in the far field region, which means that the distance between the shielding barrier and radiation source is larger than λ/2π, ...

The vector descriptions of the I and S fields are: + (A1a) (A1b) In analogy to an EM plane-wave, two plane-wave polarisations are therefore possible: a 0, log , 0 0, 0, log (A2a) b 0, 0, log 0, log , 0 (A2b) where we have generalised ...
The method of geometrical optics for unsteady media is used to represent the electric-field strength of the wave, and a transfer equation is derived by assuming that the undisturbed wave is a monochromatic plane wave that travels along the x-axis. The Fourier technique is used to solve this ...
or another accessory. The bore is the hollow length of the barrel structure through which a projectile travels when fired. An internal surface of the bore may, in embodiments, be smooth or grooved to control or otherwise enable a projection of a projectile from the chamber to a location out...
It is important to notice that the effective 2D kagome lattice has the DM interaction merely confined within the 2D plane; however, there are still interlayer exchange interactions that can affect the behaviour of the reported topological excitations and their collisions. In order to deal with this...
so that the electric and magnetic fields have solutions different from zero. This source vectorb=Qfsrcis comprised of a maskQthat separates the Total Field (TF) and the Scattered Field (SF) and an initial source fieldfsrc.In turn, the source function is defined as a plane wave so that ...
