The COordinate Rotation DIgital Computer (CORDIC) algorithm is a versatile iterative method that computes a wide range of functions – including trigonometric, hyperbolic, logarithmic and exponential – ...

In the paper, the authors present several inequalities for bounding the sums of two sine cardinal functions and the sums of two hyperbolic sine cardinal functions. These inequalities improve ...

Hyperbolic metamaterials (HMMs), which have an extremely high anisotropy with a hyperbolic dispersion relation, are rising as an innovative method of manipulating light. HMMs have received tremendous ...

"Hyperbolic metamaterials" could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. The graphic at left depicts a metamaterial's "hyperbolic ...

Researchers recently demonstrated an all-electric scheme able to flexibly control the propagation direction of near-field light. Near-field light is invisible light at the subwavelength scale.
