Multiscale Methods for Engineering Double Negative Metamaterials
The approach taken here solves the Maxwell equations inside metamaterial crystals directly and explicitly with no approximations made. The Bloch wave solution and dispersion relation is given by a power series in the ratio between wave number and period. Each term is iteratively defined by the solution of an auxiliary problem depending on the configuration and shapes of the scatterers. The lead...
متن کاملThe Quantity Lattice for Engineering
We propose a new mathematical engine for reasoning with abstraction to support engineering design. The new Quantity Lattice (ql) will be built on the foundation of the existing Quantity Lattice by Reid Simmons Simmons, 1986], the Bounder inequality reasoner by Elisha Sacks Sacks, 1987b], and the Minima hybrid real/sign algebra by Brian Williams Williams, 1991]. The new ql supports representatio...
متن کاملLattice Enumeration Using Extreme Pruning
Lattice enumeration algorithms are the most basic algorithms for solving hard lattice problems such as the shortest vector problem and the closest vector problem, and are often used in public-key cryptanalysis either as standalone algorithms, or as subroutines in lattice reduction algorithms. Here we revisit these fundamental algorithms and show that surprising exponential speedups can be achie...
متن کاملExtreme Discount Usability Engineering
This paper explores the circumstances under which extremely discounted usability engineering techniques produce results that are worthwhile to researchers and practitioners. We present a method for usability analysis where an entire evaluation can be conducted in only thirty minutes, an amount of time we suggest as perhaps the smallest possible unit of analysis (or quantum) for complete usabili...
متن کاملTwo-lattice polyhedra: duality and extreme points
Two-lattice polyhedra are a special class of lattice polyhedra that include network 4ow polyhedra, fractional matching polyhedra, matroid intersection polyhedra, the intersection of two polymatroids, etc. In this paper we show that the maximum sum of components of a vector in a 2-lattice polyhedron is equal to the minimum capacity of a cover for the polyhedron. For special classes of 2-lattice ...
