Electric Field
... Electric field lines provide a means for visualizing the direction and magnitude of electric fields. The electric field vector at any point is tangent to a field line through that point. The density of field lines in any region is proportional to the magnitude of the electric field in that region. F ...

... metal aperture to locally excite or detect an optical response. The spatial resolution in NSOM is limited to 30 – 50 nm by the penetration depth of light into the metal aperture. More recently, apertureless-NSOM (ANSOM) techniques were developed which leverage the strong enhancement of an externally ...

Space, time and Riemann zeros (Madrid, 2013)
... We are not claiming that our hamiltonian H has an immediate connection with the Riemann zeta function. This is ruled out not only by the fact that the mean eigenvalue density differs from the density of Riemann zeros after the first terms, but by a more fundamental difference in the periodic orbits. ...
