In this thesis, we prove several results concerning the shape, the modular properties, and the asymptotic behavior of the Fourier coefficients of meromorphic Jacobi forms, with applications to Lie superalgebras. By work of Kac and Wakimoto, Bringmann and Ono, Bringmann and Folsom, and Bringmann, Folsom, and Mahlburg it is known that the generating functions of Kac-Wakimoto characters relative to the $\sl(m|n)^\wedge$ superalgebra are essentially meromorphic Jacobi forms. Extending previous work of Bringmann and Folsom, we investigate Kac-Wakimoto characters for any choice of integers $m>n>0$. Subsequently, we extend the study to any single-variable meromorphic Jacobi form of positive index, and to multivariable Kac-Wakimoto characters. Finally, we investigate the asymptotic behavior of the Fourier coefficients of single-variable Kac-Wakimoto characters using a generalization of the Hardy-Ramanujan Circle Method.
