Abstract

We report on the fabrication of crossed-dipole resonant filters by direct-write electron-beam and nanoimprint lithographies. Such structures have bean used as spectrally selective components at visible, microwave; and infrared wavelengths. Imprinting is accomplished in a modified commercial hot press at 155 degreesC. The replica is then etched in oxygen plasma and developed in chlorobenzene to selectively dissolve the poly(methylmethacrylate and methacrylic acid) and poly(methylmethacrylate) bilayer resist. This step enhances undercut and improves lift-off metalization. Infrared fourier transform spectroscopy was performed to characterize the transmission response of the frequency selective surfaces (FSSs) fabricated. The resonant behavior for the direct-write FSS was found to be 5.3 mum and for the nanoimprinted FSS to be 6 mum. The shift towards longer wavelengths is consistent with the dimensions obtained for the FSSs elements in both cases. (C) 2000 American Vacuum Society. [S0734-211X(00)09706-4].
