A thin, stretchable film that coils light waves like a Slinky could one day lead to more precise, less expensive monitoring for cancer survivors.The University of Michigan chemical engineers who devel...
On solutions of Maxwell’s equations with dipole sources over a thin conducting film
solutions of Maxwell’s equations dipole sources conducting film
2015/10/16
We derive and interpret solutions of time-harmonic Maxwell’s equations with a vertical and a horizontal electric dipole near a planar, thin conducting film, e.g. Graphene sheet, lying between two unbo...
Smooth Cascade of Wrinkles at the Edge of a Floating Elastic Film
Thin polymer film liquid uniaxial compression wrinkles wrinkles model capillary force
2014/12/18
An ultrathin polymer sheet floating on a fluid forms a periodic pattern of parallel wrinkles when subjected to uniaxial compression. The wave number of the wrinkle pattern increases sharply near the f...
Quantum plasmonics: second-order coherence of surface plasmons launched by quantum emitters into a metallic film
Quantum plasmonics second-order coherence of surface plasmons quantum emitters Optics

Abstract: Purpose : To relate the physical transmittance parameters of the water equivalent Gafchromic EBT 2 Film with the delivered dose in a transparent absolute calibration protocol. The protocol s...
Birefringence induced polarization-independent and nearly all-angle transparency through a metallic film
Birefringence polarization-independent all-angle
2011/9/5
We propose an birefringence route to perfect electromagnetic (EM) wave tunneling through a metallic film which relies on homogeneous birefringent coatings with moderate and positive parameters only. E...
