Capolino, F; Jackson, DR; Wilton, DR; & Felsen, LB. (2007). Comparison of methods for calculating the field excited by a dipole near a 2-D periodic material. IEEE Transactions on Antennas and Propagation, 55(6 I), 1644-1655. doi: 10.1109/TAP.2007.897348. UC Irvine: Retrieved from: http://www.escholarship.org/uc/item/5wj468x7
A comparison of methods for calculating the field from a single dipole source in the proximity of an infinite periodic artificial material (PAM) is given. A direct plane-wave expansion method (PWM) is compared with the "array scanning method"(ASM). T

This paper is concerned with a study of the two-dimensional (2-D) time-harmonic scattering by aperiodically-ordered 1-D planar strip arrays based on two-symbol substitutional sequences, under Kirchhoff physical-optics approximation. In this connectio

In addition to being an outstanding theoretician, researcher, and educator, Prof. Felsen loved to write poetry, as evidenced by his Poet's Corner, which he regularly published in this Magazine. It is therefore fitting that our community, and this Mag

Many natural or man-made guiding environments are characterized by physical parameters that render the wave equation non-separable in any of the standard coordinate systems. In particular, in the absence of transverse-longitudinal separability, it is

This second part of a three-paper sequence deals with the spatial domain parametrization and physical interpretation of the relevant asymptotic high-frequency Green's function for a semi-infinite phased array of parallel dipoles on an infinite strati

Ray chaos, manifested by the exponential divergence of trajectories in an originally thin ray bundle, can occur even in linear electromagnetic propagation environments, due to the inherent nonlinearity of ray-tracing maps. In this paper, we present a

Ray chaos, characterized by eventual exponential divergence of originally nearby multi-bounce ray trajectories, is an intriguing phenomenon. It can be observed in several electromagnetic wave propagation scenarios: both very complex (e.g., urban area

Two-dimensional aperiodic tilings are collections of polygons, devoid of any translational symmetries, capable of covering a plane without gaps and overlaps. Although aperiodic, these structures can exhibit order and symmetry in an extended sense. In
