For many common types of process materials used in the fabrication of infrared microelectronic devices there is a lack of information available in the literature regarding their thin-film optical properties over the wavelength range of 2 to 30 microm

We compare design and measurements for a single-layer meanderline quarter-wave phase retarder, operating across the wavelength range from 8 to 12 micrometers (25 to 37.5 THz) in the infrared. The structure was fabricated using direct-write electron-b

This paper extends these initial efforts and attempts to increase the transmission and bandwidth by using multiple meanderline layers. A new ellipsometric method of characterization allows spectral measurements from 6-14 mum. The use of multiple laye

Frequency selective surfaces (FSS) are traditionally resonant periodic antenna structures patterned on a surface for the purpose of spectral filtering. At infrared (IR) frequencies, FSS structures have been successfully demonstrated as both transmiss

To the authors' knowledge this paper is the first proof of concept of using meander line structures in the infrared domain. We have fabricated a single layer gold meander line on a high resistivity silicon substrate capable of changing the polarizati

An infrared meander-line waveplate has been modeled and measured over the 8 to 12 microm spectral band in terms of its differential phase delay, axial ratio of the output polarization ellipse, and power throughput for angles of incidence between 0 de

Periodic metallic microstructures were fabricated on polyimide membranes. Techniques were developed to maintain flatness of the membrane during processing while still allowing for flexibility in the final structure. For proper functionality of the st

Meanderline wave plates are in common use at radio frequencies as polarization retarders. We present initial results of a gold meanderline structure on a silicon substrate that functions at a wavelength of 10.6 microm in the IR. The measured results
