Nonperturbative decay dynamics in metamaterial waveguides
Iñigo Liberal, Richard W. Ziolkowski
In this work we investigate the nonperturbative decay dynamics of a quantum emitter coupled to a composite right/left handed transmission line (CRLH-TL). Our theory captures the co…
Control of a quantum emitter's bandwidth by managing its reactive power
Iñigo Liberal, Iñigo Ederra, Richard W. Ziolkowski
Reactive power plays a crucial role in the design of small antenna systems, but its impact on the bandwidth of quantum emitters is typically disregarded. Here, we theoretically dem…
Superbackscattering Nanoparticle Dimers
Iñigo Liberal, Iñigo Ederra, Ramón Gonzalo +1
The theory and design of superbackscattering nanoparticle dimers are presented. We analytically derive the optimal configurations and the upper bound of their backscattering cross-…
Least Upper Bounds of the Powers Extracted and Scattered by Bi-anisotropic Particles
Inigo Liberal, Younes Ra'di, Ramon Gonzalo +3
The least upper bounds of the powers extracted and scattered by bi-anisotropic particles are investigated analytically. A rigorous derivation for particles having invertible polari…
A review of the scattering parameter extraction method with clarification of ambiguity issues in relation to metamaterial homogenization
S. Arslanagić, T. V. Hansen, N. A. Mortensen +4
The scattering parameter extraction method of metamaterial homogenization is reviewed to show that the only ambiguity is the one related to the choice of the branch of the complex…
The Design and Simulated Performance of a Coated Nano-Particle Laser
Joshua A. Gordon, Richard W. Ziolkowski
The optical properties of a concentric nanometer-sized spherical shell comprised of an (active) 3-level gain medium core and a surrounding plasmonic metal shell are investigated. C…
