Journal ArticleDOI
A selective modal scheme for the analysis of EM coupling into or radiation from large open-ended waveguides
TL;DR: In this article, a selective modal scheme is proposed to efficiently analyze the problem of high-frequency (HF) electromagnetic coupling/penetration into or radiation from open-ended waveguides.
Journal ArticleDOI
Low-threshold lasing eigenmodes of an infinite periodic chain of quantum wires
Volodymyr O. Byelobrov,Jiri Ctyroky,Trevor M. Benson,Ronan Sauleau,Ayhan Altintas,Alexander I. Nosich +5 more
TL;DR: A new effect is demonstrated: the existence of specific grating eigenmodes that have a low threshold of lasing even if the wires are optically very thin.
Journal ArticleDOI
Accurate simulation of reflector antennas by the complex source-dual series approach
TL;DR: In this article, the problem is first formulated in terms of the dual series equations and then is regularized by the Riemann-Hilbert problem technique, and the resulting matrix equation is solved numerically with a guaranteed accuracy.
Journal ArticleDOI
Wireless Displacement Sensing Enabled by Metamaterial Probes for Remote Structural Health Monitoring
Burak Ozbey,Emre Unal,Hatice Ertugrul,Ozgur Kurc,Christian M. Puttlitz,Vakur B. Erturk,Ayhan Altintas,Hilmi Volkan Demir +7 more
TL;DR: A wireless, passive, metamaterial-based sensor that allows for remotely monitoring submicron displacements over millimeter ranges and holds a great promise for applications in remote structural health monitoring.
Journal ArticleDOI
Radar cross-section study of cylindrical cavity-backed apertures with outer or inner material coating: the case of E-polarization
TL;DR: In this paper, a dual-series-based solution is obtained for the scattering of an E-polarized plane wave from a cavity-backed aperture which is formed by a slitted infinite circular cylinder coated with absorbing material.
