Gain and One-Way Propagation in Synthetically Moving non-Foster Gratings
Antonio Alex-Amor, Carlos Molero, Mario G. Silveirinha
In this paper, we analyze the electromagnetic properties of space-time grooved metal surfaces governed by uniform-velocity modulations. We begin by deriving the electromagnetic fie…
Temporal Paraxial Optics under Adiabatic Modulations
Antonio Alex-Amor, Carlos Molero
This paper presents a temporal paraxial formulation for the propagation of ultrashort optical pulses in time-modulated media with slowly varying refractive index. By deriving the p…
3-D Metamaterials: Trends on Applied Designs, Computational Methods and Fabrication Techniques
Antonio Alex-Amor, Angel Palomares-Caballero, Carlos Molero
Metamaterials are artificially engineered devices that go beyond the properties of conventional materials in nature. Metamaterials allow the creation of negative refractive indexes…
