Abstract :
This paper presents power combining of TE surface waves in a dielectric slab by a planar active lens amplifier. An amplifier gain greater than 7 dB over a 56% bandwidth has been demonstrated. Measurements of output power versus input power and surface wave field patterns are also presented.
