In this paper, we analyze the illumination by an electromagnetic wave of an air/left-handed medium (LHM) interface. It is shown that by placing a periodic structure of resistors near the LHM it is possible to suppress or to reduce the surface wave that is present at the interface. For our demonstration, we consider a semi-infinite lossless lefthanded medium having the same constitutive paramete...

On 31 December 2012, an instrumented autonomous surface vehicle (ASV; Wave Glider) transiting across the Pacific fromHawaii toAustralia as part of the PacificCrossing (PacX) project came very close (46 km) to the center of a category 3 Tropical Cyclone (TC), Freda, experiencing winds of up to 37 m s21 and significant wave heights close to 10m. The Wave Glider was instrumented for surface ocean–...

In dynamic analysis of floating structures, the designer needs to know the wave forces due to incident and scattered waves on the structure. In this work, the flow field around the body is solved based on the potential theory with considering the free surface and sea bed effects. Using this theory, the wave forces exerted on two typical sea buoys with spherical and disc-type bodies are determin...

The characteristics of dielectric backed planar conducting layers of arbitrarily shaped in a rectangular waveguide are calculated by means of coupled integral equation technique (CIET) which accurately takes higher order mode interactions. Equivalent structures for the accurate analysis whole structure are introduced in which magnetic surface currents are identified as the unknowns at the apert...

We review the properties of solar convection that are directly observable at the solar surface, and discuss the relevant underlying physics, concentrating mostly on a range of depths from the temperature minimum down to about 20 Mm below the visible solar surface. The properties of convection at the main energy carrying (granular) scales are tightly constrained by observations, in particular by...
