dc.description.abstract	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.	uk_UA
dc.description.sponsorship	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.
