Waveguide Modes in Weyl Semimetals with Tilted Dirac Cones
Klaus Halterman, Mohammad Alidoust
We theoretically study unattenuated electromagnetic guided wave modes in centrosymmetric Weyl semimetal layered systems. By solving Maxwell's equations for the electromagnetic fiel…
Dynamical tuning between nearly perfect reflection, absorption, and transmission of light via graphene/dielectric structures
Jacob Linder, Klaus Halterman
Exerting well-defined control over the reflection , absorption , and transmission of electromagnetic waves is a key objective in quantum optics. To this end, one of…
Graphene-based extremely wide-angle tunable metamaterial absorber
Jacob Linder, Klaus Halterman
We investigate the absorption properties of graphene-based anisotropic metamaterial structures where the metamaterial layer possesses an electromagnetic response corresponding to a…
Near-perfect absorption in epsilon-near-zero structures with hyperbolic dispersion
Klaus Halterman, J. Merle Elson
We investigate the interaction of polarized electromagnetic waves with hyperbolic metamaterial structures, whereby the in-plane permittivity component is opposite in sign to…
Perfect Absorption in Ultrathin Epsilon-Near-Zero Metamaterials Induced by Fast-Wave Non-Radiative Modes
Simin Feng, Klaus Halterman
Above-light-line surface plasmon polaritons can arise at the interface between a metal and epsilon-near-zero metamaterial. This unique feature induces unusual fast-wave non-radiati…
Exotic leaky wave radiation from anisotropic epsilon near zero metamaterials
Klaus Halterman, Simin Feng, Viet Cuong Nguyen
We investigate the emission of electromagnetic waves from biaxial subwavelength metamaterials. For tunable anisotropic structures that exhibit a vanishing dielectric response along…
Mode Bifurcation and Fold Points of Complex Dispersion Curves for the Metamaterial Goubau Line
P. L. Overfelt, Klaus Halterman, Simin Feng +1
In this paper the complex dispersion curves of the four lowest-order transverse magnetic modes of a dielectric Goubau line () are compared with those of a dispersive meta…
Discrete Cylindrical Vector Beam Generation from an Array of Optical Fibers
R. Steven Kurti, Klaus Halterman, Ramesh K. Shori +1
A novel method is presented for the beam shaping of far field intensity distributions of coherently combined fiber arrays. The fibers are arranged uniformly on the perimeter of a c…
Exotic Grazing Resonances in Nanowires
Simin Feng, Klaus Halterman
We investigate electromagnetic scattering from nanoscale wires and reveal for the first time, the emergence of a family of exotic resonances, or enhanced fields, for source waves c…
Resonant Transmission of Electromagnetic Fields through Subwavelength Zero- Slits
Klaus Halterman, Simin Feng
We theoretically investigate the transmission of electromagnetic radiation through a metal plate with a zero- metamaterial slit, where the permittivity tends towards zero over a…
Subwavelength fractional Talbot effect in layered heterostructures of composite metamaterials
Simin Feng, Klaus Halterman, Pamela L. Overfelt
We demonstrate that under certain conditions, fractional Talbot revivals can occur in heterostructures of composite metamaterials, such as multilayer positive and negative index me…
Characteristics of bound modes in coupled dielectric waveguides containing negative index media
Klaus Halterman, J. Merle Elson, P. L. Overfelt
We investigate the characteristics of guided wave modes in planar coupled waveguides. In particular, we calculate the dispersion relations for TM modes in which one or both of the…
