We present a modeling approach for predicting spatially-resolved properties of polycrystalline ceramics. The model yields excellent agreement with experimental results obtained for Al2O3, Ce-doped Y3Al5O12 and ZnS. Simulations of the transmission modulation under applied electromechanical fields predict switching from full transparency to opacity, in some instances. The results of this investigation highlight a remarkable promise of functional microceramics for a range of advanced applications.
