Abstract :
Artificial dielectric technology is used in the realisation of the transverse modulation of refractive index to fabricate a thick volume hologram for microwave- and millimetre-wave applications. A prototype is fabricated accordingly and tested to verify the concept. This is believed to be the first time that a thick volume hologram is implemented for application in microwave and millimetre-wave frequency bands.
