Inverse‐designed gyrotropic scatterers for non‐reciprocal analog computing
Nanophotonics, Volume 14, Issue 27, Page 5011-5021, December 2025.Abstract While conventional von Neumann based machines are increasingly challenged by modern day requirements, electromagnetic analog computing devices promise to provide a platform that is highly parallel, efficient and fast. Along this paradigm, it has been shown that arrays of subwavelength electromagnetic scatterers can be used as solvers of ...

On Rayleigh-Ritz Method in Three-Parameter Eigenvalue Problems
, 2014 This paper deals with the computation of the eigenvalues of a three-parameter Sturm-Liouville problem in the form of ordinary differential equation using Rayleigh-Ritz Method, a method which is based on the principle of variational methods.

Quasicomparison Functions and Substructure Synthesis for Framed Structures Stability Analysis
Latin American Journal of Solids and StructuresThe Rayleigh-Ritz-Meirovitch substructure synthesis method (RRMSSM) is extended to buckling analysis in framed structures. The objective is a computational procedure capable of yielding very accurate critical loads through solution of very-low-order ...
