Plasma spraying of anti-reflection (AR) coatings onto high permittivity microwave ceramics is a very attractive novel technique for minimizing reflections from optical components. This technique should be able to supersede conventional solutions to the loss of power by reflections, such as the ‘moth-eye’ AR surface (see Figure). Plasma spraying avoids the machining problems presented by the size and spacing of the protuberances required for ‘moth-eye’ AR surfaces for microwave optical ceramic components.
