Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

open access: yesAdvanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

Modeling and Improving Geometric Accuracy in Projection Multiphoton Lithography

open access: yesAdvanced Optical Materials, EarlyView.
A numerical framework describing the optical and photochemical processes is developed to elucidate the origins of geometric deviations in projection multiphoton lithography. The results indicate that oxygen diffusion and inhibition, and DMD diffraction, lead to geometric distortions.

Numerical solution to nonlinear Tricomi equation using WENO schemes

open access: yesElectronic Journal of Differential Equations, 2010
Nonlinear Tricomi equation is a hybrid (hyperbolic-elliptic) second order partial differential equation, modelling the sonic boom focusing. In this paper, the Tricomi equation is transformed into a hyperbolic system of first order equations, in ...

Errata: Periodic Solutions of Hyperbolic Partial Differential Equations [PDF]

open access: yesProceedings of the American Mathematical Society, 1966
It is well known that, if in addition to usual smoothness conditions, the functions f and the prescribed data u0(x) are periodic in x with the same period T, then there exists a solution u(x, y) of (1.1) satisfying u(x, 0)=u0(x), u(0, y)=vo(y)+uo(0), where vo(0)=0 for xC-(-oo,oo) and yCE[-a, a].

Accelerating Luminescence in Nanostructures: Exploring the Physical Limits and Impact of Ultrafast Emission in Nanoscale Materials

open access: yesAdvanced Photonics Research, EarlyView.
This review highlights recent advances in accelerating luminescence in nanostructures through cooperative emission, resonator coupling, and nonlocal light–matter interactions. By unifying concepts such as excitonic superradiance, superfluorescence, and the plasmonic Purcell effect, it reveals physical limits of ultrafast emission and their potential ...
