TY - JOUR AU1 - Vizard, David AB - The millimeter-wave part of the electromagnetic spectrum generally means that range of wavelengths from near 1 mm to 10 mm, or frequencies from 30 GHz to just above 300 GHz. Millimetre-wave systems designers face severe difficulties in obtaining high performance from components and waveguide transmission media at frequencies above 100 GHz. Sub-millimetre and far-infrared systems or receivers use optical techniques to obtain low-loss transmission and coupling to antennas and sensors. For the engineer or electronic physicist with a conventional training, microwaves and optics tend to be treated as distinct subjects. Millimetre-wave applications, however, merge these subjects in a way that demonstrates elegantly their underlying physical unity.
