Periodic structures involving crossed arrays of cylinders appear as special three-dimensional photonic crystals and cross-stacked gratings. Such a structure consists of a number of layers where each layer is periodic in one spatial direction and invariant in another direction. They are relatively simple to fabricate and have found valuable applications. For analyzing scattering properties of su...

We study electromagnetic forces and torques on a discrete spherical invisibility cloak under time-harmonic illumination. We consider the influence of material absorption and losses, and we show that while the impact of absorption on the optical force remains confined to frequencies near the absorption peak, its impact on the electromagnetic torque experienced by the cloak is spectrally broader ...

Understanding the structure of a scattered electromagnetic (EM) field is critical to improving the imaging process. Mechanisms such as diffraction, scattering, and interference affect an image, limiting the resolution, and potentially introducing artifacts. Simulation and visualization of scattered fields thus plays an important role in imaging science. However, EM fields are high-dimensional, ...

We present a summary of the results of two recent precise calculations of the muon anomalous magnetic moment and the electromagnetic coupling on the Z.

− This paper presents results from calculating the radar cross section (RCS) of two maritime radar reflectors using the method of moments. The Echomaster 152, although smaller in size, produces a higher maximum RCS than the Echomax 230 that includes three layers of corner reflectors. The Echomaster 152 also has deeper nulls in the RCS pattern, which means it is less detectable at those angles.
