We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two types of metamaterials, layered highly doped/undoped heterostructures and quantum well superlattices that are highly anisotropic. Contrary to other...
Eleven species of Mononchidae Chitwood, 1937 were
found among the nematodes separated from 48 soil samples
in Thailand and sent to Oregon State University. Six
species are newly described and illustrated including
Iotonchus bangkokensis, Iotopchus ainostomos, Iotonchus
chantabunensis, Iotonchus ravonqensis, fotonchus thai-Iandensis, and Miconchus triodontus. Also reported is a
