We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...

The Auckland aggregate market is estimated to be 7.2 million tonnes a year. Sixteen major quarries supply this market. Because of the number of suppliers and the variety of products, planning in this complex environment is difficult. Winstone Aggregates is the largest producer of rock products in Auckland. It owns nine quarries and supplies slightly more then half of the region's aggregate need...
