Abstract
We discuss the thermal Casimir effect in a thin hybrid nematic cell, and we analyse the enhancement of the fluctuation-mediated force due to the frust rating effect of competing surface interactions. The force exhibits a non-a lgebraic and non-monotonic dependence on the distance, and it dominates the total structural interaction in the system. Similar behaviour is found in the Friedericksz cell, characterized by a bulk destabilizing external force .
