AB - The paper proposes a general framework allowing the analysis of wetting problems in the
situation when interfacial tensions depend on external fields. An equation predicting
apparent contact angles of sessile droplets deposited on rough surfaces in the presence of
external fields is derived. The problem of wetting is discussed in the framework of the
variational approach. Derivation of a general equation generalizing the Cassie and Wenzel
approaches is presented. The effects related to the line tension which are important for
nano-structured surfaces are considered.
