Transport of waves plays an important role in modern communication systems like Wi-Fi or optical fibres. Typical problems in such systems concern security against possible intruders, energy consumption, time efficiency and the possibility of mode filtering. Microwave experiments are suited to study this kind of problems, because they offer a...

Since their spectacular experimental realisation in the early 80's, quasicrystals have been the subject of very active research, whose domains extend far beyond the scope of solid state physics. In optics, for instance, photonic quasicrystals have attracted strong interest for their specific behaviour, induced by the particular spectral...

A series of quantum search algorithms has been proposed recently providing an algebraic speed-up compared to classical search algorithms from N to N where N is the number of items in the search space. In particular, devising searches on regular lattices have become popular extending Grover's original algorithm to spatial searching. Working in a...
