ELECTROMAGNETIC FIELDS INDUCED BY SURFACE RING WAVES IN THE DEEP SEA

Depolarization of Electromagnetic Waves By Sea Surface

An improved Two Scale Model (TSM) has been investigated for the depolarization of electromagnetic waves from sea surface. Classical TSM produce depolarized results due to the tilt of reflecting plane. To include the contribution of actual phenomenon we add the second order scattering effects at small scale and develop an improved TSM. Numerical results are obtained for both backscattering and b...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

The effect of Cannabis sativa extract on damages induced by electromagnetic fields on ovarian follicle maturation and hormonal surface changes in mice

Electromagnetic waves (EMF) are a mixture of electrical and magnetic waves. The energy transmitted by these radiations is absorbed by living tissues. Electromagnetic fields seem to cause infertility in women. Cannabis is annual herbaceous plant grows in tropical areas. This study was conducted to investigate the protective effects of hydroalcoholic extract of Cannabis sativa in various doses of...

Propagation and Interaction of Electrostatic and Electromagnetic Waves in Two Stream Free Electron Laser in the Presence of Self-Fields

A relativistic theory for two-stream free electron laser (FEL) with a one-dimensional helical wiggler and ion-channel guiding in the presence of self-fields are presented. A dispersion relation (DR) which includes coupling between the electromagnetic and the electrostatic waves is derived from a fluid model, with all of the relativistic terms related to the transverse wiggler motion. This DR is...
