  We study the transmission coefficient and the transmitted power through an
SMS sensor with transverse misalignment. We use the Finite Element Method to
calculate the modes distribution by numerically solving the wave equation. The
results show that the maximum transmission can be obtained when the
misalignment is greater than zero due to the $n \neq m$ LP$_{nm}$ excited
modes. Additionally, the transmitted power as function of the temperature shows
that it is significant only in the aligned case.
