Optical transmittance of photonic structures with linearly graded dielectric constituents
TL;DR: In this paper, the optical transmittance of one-dimensional photonic structures generated from lossless dielectric slabs with linear, or piecewise linear, profiles of their electric permittivity for linearly polarized, normally incident electromagnetic radiation is studied both analytically and numerically.

Electromagnetic Scattering by a Metallic Spheroid Using Shape Perturbation Method
TL;DR: In this paper, the scattering of a plane electromagnetic wave by a perfectly conducting prolate or oblate spheroid is considered analytically by shape perturbation method, and exact closed-form expressions for the expansion coefficients g(2) and g(4) in the relation S(h) = S(0)[1 + g (2)h2 + g( 4)h4 + O(h6)] expressing the scattering cross-sections.

Strong lateral displacement in polarization anisotropic extraordinary transmission metamaterial
TL;DR: In this paper, a deep numerical and experimental study of the anisotropic response of extraordinary transmission metamaterials constructed by stacking subwavelength hole arrays is presented, and it is shown that double periodic and dielectric loaded hole arrays are optimal to enlarge the numerical aperture that leads to negative refraction.

Cross-borehole sensing: identification and localization of underground tunnels in the presence of a horizontal stratification
G.A. Ellis,Irene C. Peden +1 more
TL;DR: It is shown that use of the positive spatial frequency components of the fields scattered by the buried target, together with the backpropagation of vertical cross-polarized fields, yield results that are relatively insensitive to the presence of the horizontal stratification.
