Analysis of Time-domain Electromagnetic Scattering Problem by Multiple Cavities

Electromagnetic Scattering by Multiple Cavities Embedded in the Infinite 2D Ground Plane

─ This paper is concerned with the mathematical analysis and numerical computation of the electromagnetic wave scattering by multiple open cavities, which are embedded in an infinite two-dimensional ground plane. By introducing a new transparent boundary condition on the cavity apertures, the scattering problem is reduced to a boundary value problem on the two-dimensional Helmholtz equation imp...

Electromagnetic Scattering by Open-Ended Cavities: An Analysis Using Precorrected-FFT Approach

-In this paper, the precorrected-FFT method is used to solve the electromagnetic scattering from twodimensional cavities of arbitrary shape. The integral equation is discretized by the method of moments and the resultant matrix equation is solved iteratively by the generalized conjugate residual method. Instead of directly computing the matrix-vector multiplication, which requires 2 N operation...

Time domain analysis of scattering by a water droplet.

Rainbows, coronas and glories are caused by the scattering of sunlight from water droplets in the atmosphere. Although these optical phenomena are seen fairly frequently, even scientifically minded people sometimes struggle to provide explanations for their formation. This paper offers explanations of these phenomena based on numerical computations of the scattering of a 5 fs pulse of red light...

Electromagnetic Scattering from Multiple Cylinders

During the last several decades, electromagnetic scattering from multiple cylinders has been an active research topic of in many areas, such as microwave remote sensing, theory of photonic crystals, atmospheric sciences, and so on. Rigorous theoretical treatment is therefore of critical importance. A large body of available studies in the literature concerns with two dimensional scattering, suc...
