Lens (in radio)

A structure substantially transparent to radio waves but which inserts a non-uniform phase delay over the cross-section of an aperture so as to effect a convergence (or divergence) of the radio wave. Such structures may employ dielectric or metallic configurations.

Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
