Identification for General Degenerate Problems of Hyperbolic Type
Bruno Pini Mathematical Analysis Seminar, 2016 A degenerate identification problem in Hilbert space is described, improving a previous paper [2]. An application to second order evolution equations of hyperbolic type is given.

Energy decay for hyperbolic systems of second-order equations
Journal of Mathematical Analysis and Applications, 1988 This paper deals with the solutions in the form \(U(x,t)\equiv col[U'(x,t),U^ 2(x,t),...,U^ m(x,t)]\), \(m\geq 1\), of the initial- boundary value problem \[ {\mathcal L}U\equiv \nabla^{(4)'}(A\nabla^{(4)}U)+(b'-a'_ t)\nabla U+(\quad d_ t- e)U_ t-fU=0,\quad (x,t)\in V\times [0,\infty), \] \[ U(x,t)=0,\quad (x,t)\in \partial V\times [0,\infty),\quad U(x,

Development of High‐Performance Multilayer Monochromators
Advanced Optical Materials, EarlyView.Detailed insights into the optical and multilayer design of Double Multilayer Monochromators (DMM) are presented and fully characterized, including key optimization strategies and solutions to fabrication challenges. By integrating in‐house Ion Beam Figuring and a high uniformity multilayer coating process, the developed DMMs achieve high reflectivity,

A priori estimate for discontinuous solutions of a second order linear hyperbolic problem
Electronic Journal of Qualitative Theory of Differential Equations, 2010 In the paper we investigate a non-local contact-boundary value problem for a system of second order hyperbolic equations with discontinuous solutions. Under some conditions on input data, a priori estimate is obtained for the solution of this problem.

Advanced Optical Materials, EarlyView.A comparative study of the optical and polaritonic properties of excitons in hBN‐encapsulated monolayer TMDs close to the homogeneous linewidth is presented. Reflection spectroscopy with transmission‐line modeling enables extraction of the complex permittivities and demonstrate their ability to host surface‐exciton‐polaritons.

Electronic Journal of Differential Equations, 2012 We study strictly hyperbolic partial differential operators of second-order with non-smooth coefficients. After modeling them as semiclassical Colombeau equations of log-type we provide a factorization procedure on some time-space-frequency domain. As

Cauchy problem for a linear hyperbolic equation of the second order
Mathematical Modelling and Analysis, 2006 The definition of hyperbolic equation by a prescribed vector field is introduced for linear differential equation of the second order. The Cauchy problem with prescribed boundary conditions is considered for such equations.

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