We discuss the issue of identifying the forward/backward nature of modes in bounded one-dimensional periodic structures. This identification is based on the possibility of adequately and uniquely defining the phase velocity in these types of structur

The Physical Optics (PO) method is used to derive simplified expressions to compute the radiation electric fields of planar graded-index and geodesic lenses based on a parallel-plate waveguide (PPW) implementation. If the PO method is combined with r

The relationship of the poetic sheets 90*AD and 93*CA, which contains the Latin text of the Disticha Catonis, together with the Disticha Moralia, printed by Hurus around 1488, is studied in this paper. By this way, the arguments of the filiation of 9

The presence of glide symmetries in periodic structures can introduce beneficial modifications in their electromagnetic properties. The difference between glide and non-glide periodic structures is due to the distinctive coupling between their consti
