ABSTRACT: In this present work, we consider an eigenvalue-type problem involving the p-Laplacian operator under nonlinear boundary conditions, in case g≡0 , and we prove the existence of an isolated ...

Abstract: A novel full-structure characteristic modes (CMs) equation for composite objects is developed in this paper. The novel generalized eigenvalue equation (GEE) is valid for any number of ...

Physicists have proposed modifications to the infamous Schrödinger's cat paradox that could help explain why quantum particles can exist in more than one state simultaneously, while large objects ...

Abstract: A nested iterative solver for the generalized eigenvalue equation of the volume surface integral equation-based substructure is proposed for characteristic mode analysis of composite ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

School of Mechanical Engineering, Hebei University of Technology, Tianjin, China This paper presents a polynomial eigenvalue solution to predict the propagation behaviors of elastic wave in ...

I am working on finding resonant modes of a Maxwell system, and I would like to make part of the domain (slightly) conducting. This would introduce a loss mechanism in the physical system, so the ...

Coarse-mesh finite difference (CMFD) method is a widely used numerical acceleration method. However, the stability of CMFD method is not good for the problems with optically thick regions. In this ...
