Line Degeneracy and Strong Spin-Orbit Coupling of Light with Bulk
... By using the retrieved effective parameters of the metamaterial at 6.1 GHz, we obtain a very small ratio between the cross and the cocircular polarization transmission δ ≈ 0.004, indicating that a circularly polarized incident light only couples to the propagating mode of the same helicity. This is ...

Thomas Young (scientist)
.jpg?width=300)
Thomas Young (13 June 1773 – 10 May 1829) was an English polymath and physician. Young made notable scientific contributions to the fields of vision, light, solid mechanics, energy, physiology, language, musical harmony, and Egyptology. He ""made a number of original and insightful innovations""in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollion eventually expanded on his work. He was mentioned by, among others, William Herschel, Hermann von Helmholtz, James Clerk Maxwell, and Albert Einstein. Young has been described as ""The Last Man Who Knew Everything"".
