Controlled microwave heating in modern organic synthesis.
Although fire is now rarely used in synthetic chemistry, it was not until Robert Bunsen invented the burner in 1855 that the energy from this heat source could be applied to a reaction vessel in a focused manner. The Bunsen burner was later superseded by

Vortices at Microwave Frequencies [PDF]
AbstractThe behavior of vortices at microwave frequencies is an extremely useful source of information on the microscopic parameters that enter the description of the vortex dynamics. This feature has acquired particular relevance since the discovery of unusual superconductors, such as cuprates.

Wideband planar dipole based on dual-layer artificial magnetic conductor
A wideband planar dipole based on dual-layer artificial magnetic conductor (AMC) is designed. First, the size of dual-layer AMC is reduced by more than half, and the in-phase band is wider than the single-layer AMC.
