The authors respectfully dedicate this paper to the
blessed memory of their beloved Teacher, a prominent
Ukrainian physicist K.B. Tolpygo, who has made an immense
contribution to theoretical foundations of lightmatter
coupling. Kirill Borisovich has influenced our
scientific formation for which we are endlessly grateful.

We develop a numerical model for a defect-containing square lattice of microcavities with embedded ultracold atomic clusters (quantum dots). It is assumed that certain fractions of quantum dots and cavities are absent, which leads to transformation of polariton spectrum of the overall structure. The dispersion relations for polaritonic modes are derived as functions of defect concentrations and on this basis the band gap, the effective masses of lower and upper dispersion branch polaritons as well as their densities of states are evaluated.
