We show that for strictly concave domains there are no interior transmission eigenvalues in a region of the form $$\left\{ \lambda \in \mathbf{C}:\mathrm{Re}\,\lambda \ge 0,\,\,|\mathrm{Im}\,\lambda |\ge C_\varepsilon \left( \mathrm{Re}\,\lambda +1\right) ^{\frac{1}{2}+\varepsilon }\right\} $$λ∈C:Reλ≥0,|Imλ|≥CεReλ+112+ε, $$C_\varepsilon >0$$Cε>0, for every $$0<\varepsilon \ll 1$$0<ε≪1. As a consequence, we obtain Weyl asymptotics for the number of the transmission eigenvalues with an almost optimal remainder term.
