Modeling dispersive silver in the electrodynamic lattice-Boltzmann method using complex-conjugate pole-residue pairs
Cael Warner, Loïc Markley, Kenneth J. Chau
The polarization density of a broadband electrodynamic lattice-Boltzmann method (ELBM) is generalized to represent frequency-dispersion of materials interacting with electromagneti…

Flat Lens Criterion by Small-Angle Phase
Peter Ott, Mohammed H. Al Shakhs, Henri J. Lezec +1
We show that a classical imaging criterion based on angular dependence of small-angle phase can be applied to any system composed of planar, uniform media to determine if it is a f…

Fourier-Domain Electromagnetic Wave Theory for Layered Metamaterials of Finite Extent
Kenneth J. Chau, Mohammed H. Al Shakhs, Peter Ott
The Floquet-Bloch theorem allows waves in infinite, lossless periodic media to be expressed as a sum of discrete Floquet-Bloch modes, but its validity is challenged under the reali…
