Abstract
The viability of sculptured thin film (STF) implementations of Solc fan and folded filters for optical detection and determination of gas concentration is established. A nanoscopic-to-continuum model is devised for predicting the electromagnetic (optical) response of a STF Solc filter whose void regions are filled with a chemically non-reacting gas. Ultra-narrow band-pass features in the transmission spectrum are shown to shift with the gas concentration.
