Charged-Particle Scattering in the Presence of a Strong Electromagnetic Wave

Unlimited Acceleration of a Charged Particle by an Electromagnetic Wave with a Purely Transverse Electric Field

It is shown that a charged particle can be trapped in a magnetic neutral sheet produced by the combination of a static magnetic field B 0 and an electromagnetic wave propagating perpendicularly to B0 with its magnetic field component parallel to B0. The neutral sheet as well as the trapped particle moves with the phase velocity ofthe wave and the trapped particle feels a constant force. Once th...

On the Scattering of Electromagnetic Waves by a Charged Sphere

Scattering of electromagnetic radiation by a charged homogeneous spherical particle/body is treated. Theoretical solution represents a generalization of the Mie’s scattering theory for electrically neutral sphere. It is shown that classical and quantum physics approaches may lead to different conclusions, as documented by numerical computations assuming various permeabilities, refractive indice...

a generalization of strong causality

در این رساله t_n - علیت قوی تعریف می شود. این رده ها در جدول علیت فضا- زمان بین علیت پایدار و علیت قوی قرار دارند. یک قضیه برای رده بندی آنها ثابت می شود و t_n- علیت قوی با رده های علی کارتر مقایسه می شود. همچنین ثابت می شود که علیت فشرده پایدار از t_n - علیت قوی نتیجه می شود. بعلاوه به بررسی رابطه نظریه دامنه ها با نسبیت عام می پردازیم و ثابت می کنیم که نوع خاصی از فضا- زمان های علی پایدار, ب...

Calculation of Electromagnetic Wave Scattering by a Small Impedance Particle of an Arbitrary Shape

Scattering of electromagnetic (EM) waves by small (ka ≪ 1) impedance particle D of an arbitrary shape, embedded in a homogeneous medium, is studied. Analytic formula for the scattered field is derived. The scattered field is of the order O(a2−κ), where κ ∈ [0, 1) is a number. This field is much larger than in the case of Rayleigh-type scattering. The numerical results demonstrate a wide range o...
