  In this paper, we study the electromagnetic Casimir effects in the context of
Lorentz symmetry violations. Two distinct approaches are considered: the first
one is based on Horava-Lifshitz methodology, which explicitly presents a
space-time anisotropy, while the second is a model that includes
higher-derivatives in the field strength tensor and a preferential direction in
the space-time. We assume that the electromagnetic field obeys the standard
boundary conditions on two large parallel plates. Our main objectives are to
investigate how the Casimir energy and pressure are modified in both Lorentz
violation scenarios.
