Time derivatives via interconnected waveguides
Ross Glyn MacDonald, Alex Yakovlev, Victor Pacheco-Peña
Electromagnetic wave-based analogue computing has become an interesting computing paradigm demonstrating the potential for high-throughput, low power, and parallel operations. In t…
Neural network design of multilayer metamaterial for temporal differentiation
Tony Knightley, Alex Yakovlev, Victor Pacheco-Peña
Controlling wave-matter interactions with metamaterials (MTMs) for the calculation of mathematical operations has become an important paradigm for analogue computing given their ab…
Effective Local Permittivity Model for Non-Local Wire Media
Alexander B. Yakovlev, Mário G. Silveirinha, George W. Hanson
A local permittivity model is proposed to accurately characterize spatial dispersion in non-local wire-medium (WM) structures with arbitrary terminations. A closed-form expression…
An Equivalent ABCD-Matrix Formalism for Non-Local Wire Media with Arbitrary Terminations
Alexander B. Yakovlev, Mário G. Silveirinha, George W. Hanson +1
A simple analytical model based on the transmission-matrix approach is proposed for equivalent wire-medium (WM) interfaces. The obtained ABCD matrices for equivalent interfaces cap…
Exceptional Points of Degeneracy and Branch Points for Transmission-Line Problems - Linear Algebra and Bifurcation Theory Perspectives
George W. Hanson, Alexander B. Yakovlev, Mohamed Othman +1
We demonstrate several new aspects of exceptional points of degeneracy (EPD) pertaining to propagation in two uniform coupled transmission-line structures. We describe an EPD using…
A planar hyperlens based on a modulated graphene monolayer
Ebrahim Forati, George W. Hanson, Alexander B. Yakovlev +1
The canalization of terahertz surface plasmon polaritons using a modulated graphene monolayer is investigated for subwavelength imaging. An anisotropic surface conductivity formed…
