WebMar 7, 2011 · In this work, we report a nature indefinite permittivity in crystalline graphite that exhibits negative group refraction at ultraviolet region. A hyperbolic equifrequency contour was obtained from ellipsometry data at 254 nm and an all angle negative refraction was verified experimentally. The indefinite permittivity is attributed to extremely strong … WebCast irons: addition of Si- catalyzes graphite formation Generically, a ferrous alloy, the carbon content of which is greater than the maximum solubility in austenite at the eutectic temperature.
