In this paper we present a mode-matching technique to study the transmission coefficient of mesoscopic devices such as electron waveguides in the presence of high magnetic fields for different situations. A detailed study of the difficulties rising due to the presence of the magnetic field is given and the differences with the zero magnetic field case are stressed. We apply this technique to calculate the transmission at non-zero magnetic field of two completely different systems: a) a quantum box built up on a quantum wire (or electron waveguide) by means of two barriers and b) a meandering quantum wire, {\em i.e.}, a wire with changes in the guiding direction. In the former case we analyze the so-called {\em Coulomb Blockade} and {\em Aharanov-Bohm} regimes and in the latter one we focus on the realistic case of soft, circular bends joining the different sections of the wire.
