## Abstract The scattering and radiation characteristics of a step discontinuity in a doubleβnegative (DNG) slab waveguide operating in the evanescent surface mode are analyzed by a method which combines the rigorous modeβmatching method with multimode network theory. In the analysis, the radiation
Evanescent waves are characterized by the exponential decay of the amplitude along the propagation direction, such that no phase velocity could be properly defined and the concept of propagation itself has to be properly redefined. However, evanescent waves can carry energy beyond a tunneling region
