Abstract :
A new type of lens is proposed which is effective for surface waves on dielectric slabs at millimetre wavelengths. The lens consists of two identical metallic plates of double convex shape which sandwlch the dielectric slab between them. It is demonstrated that a periodic sequence of the lenses can guide surface beam waves efficiently.
