Inspired by a result of Wong (Partial Differ Equ 13(10):1209–1221, 1988), we establish an analytic description of the essential spectrum of non-self-adjoint mixed-order systems of pseudo-differential operators on L² (RN) ⊕ L²(RN) that are uniformly Douglis–Nirenberg elliptic with positive-order diagonal entries. We apply our result to a problem arising in the dynamics of falling liquid films.
