Spectral asymptotic in the large coupling limit
(58K, Latex 2e)

ABSTRACT.   In this paper, we study a singular perturbation of an eigenvalues 
problem related to supra-conductor wave guides. Using boundary 
layer tools we 
perform a complete asymptotic expansion of the eigenvalues as the conductivity 
tends to $+\infty$.
