Electromagnetic imaging of separable obstacle problem

Problem with Separable Potentials

The low energy three nucleon problem with two particle separable potentials is solved. The formalism of Faddeev in recasting the three body equations into Fredholm form and subsequent angular momentum reductions are carried out. Upon searching for a bound state two poles of the amplitude are found. Upon further examination one of the poles is found to have a residue of the wrong sign. This diff...

On uniqueness of an inverse problem in electromagnetic obstacle scattering for an impedance cylinder

We consider an inverse problem for the scattering of an obliquely incident electromagnetic wave by an impedance cylinder. In previous work, we have shown that the direct scattering problem is governed by a pair of Helmholtz equations subject to coupled oblique boundary conditions, where the wave number depends on the frequency and the incident angle with respect to the axis of the cylinder. In ...

the problem of divine hiddenness

این رساله به مساله احتجاب الهی و مشکلات برهان مبتنی بر این مساله میپردازد. مساله احتجاب الهی مساله ای به قدمت ادیان است که به طور خاصی در مورد ادیان ابراهیمی اهمیت پیدا میکند. در ادیان ابراهیمی با توجه به تعالی خداوند و در عین حال خالقیت و حضور او و سخن گفتن و ارتباط شهودی او با بعضی از انسانهای ساکن زمین مساله ای پدید میاید با پرسشهایی از قبیل اینکه چرا ارتباط مستقیم ویا حداقل ارتباط وافی به ب...

Random Homogenization of an Obstacle Problem

We study the homogenization of an obstacle problem in a perforated domain, when the holes are periodically distributed and have random shape and size. The main assumption concerns the capacity of the holes which is assumed to be stationary ergodic.
