This essentially numerical study, sets out to investigate various geometrical properties of exact boundary controllability of the wave
equation when the control is applied on a part of the boundary. Relationships between the geometry of the domain, the geometry of
the controlled boundary, the time needed to control and the energy of the control are dealt with. A new norm of the control and an
energetic cost factor are introduced. These quantities enable a detailed appraisal of the numerical solutions obtained and the detection
of trapped rays.
