On the spectrum of a nontypical eigenvalue problem

We study a nontypical eigenvalue problem in a bounded domain from the Euclidian space $\mathbb{R}^2$ subject to the homogeneous Dirichlet boundary condition. We show that the spectrum of the problem contains two distinct intervals separated by an interval where there are no other eigenvalues.
