【 摘 要 】

Plane-wave reflection and refraction at an interface with a double-wire medium is considered. The problem of additional boundary conditions (ABC) in application to wire media is discussed and an ABC-free approach, known in the solid state physics, is used. Expressions for the fields and Poynting vectors of the refracted waves are derived. Directions and values of the power density flow of the refracted waves are found and the conservation of the power flow through the interface is checked. The difference between the results given by the conventional model of wire media and the model, properly taking into account spatial dispersion, is discussed.
