Multi-layer anti-reflection coats using ePTFE membrane for mm-wavelength plastic optics
Miranda Eiben, Keara Carter, Marion Dierickx +7
Future millimeter wavelength experiments aim to both increase aperture diameters and broaden bandwidths to increase the sensitivity of the receivers. These changes produce a challe…
