Gallant, A.J. and Levitt, J.A. and Kaliteevski, M. and Wood, D. and Petty, M.C. and Abram, R.A. and Brand, S. and Chamberlain, J.M. (2006) 'Enhanced THz transmission apertures through sub-wavelength annular apertures.', Proceedings of SPIE., 6323 . p. 632316.
We report on the development of a surface micromachined process for the fabrication of coaxial apertures surrounded by periodic grooves. The process uses a combination of copper electroforming and the negative epoxy based resist, SU8, as a thin flexible substrate. The device dimensions are suitable for the implementation of filters at THz frequencies, and measurements show a pass band centred around 1.5 THz. These devices could form the basis of the next generation of THz biosensors.
