✦ Synopsis

This paper deals with lattices of plates connected at a non-zero angle. The purpose is not only to identify the usual behaviour of lattices of plates (where pass-bands and stop-bands appear) but also to explain the rise of the amber-band. The notion of hypersensitivity existing for the case of two plates still exists for the case of a lattice of plates. When dealing with a lattice of identical systems, it is usual to observe the behaviour when some defects are included. This kind of study is proposed in this work, and some rules describing the rise of effects due to angular defects at a connection angle are proposed. A study focusing on a lattice of different coupled plates, is also proposed; a numerical approach shows results which could be suitable for an experimental tool detecting hypersensitive connections.
