Hypersonic rugate filters based on porous silicon

Hypersonic rugate filters based on porous silicon

Periodic solid state structures exhibit transmission stopbands for waves of certain frequencies. We demonstrate porous silicon based rugate filters with 40 dB rejection first-order stopbands for longitudinal acoustic waves at hypersonic frequencies and the predicted suppression of higher order bands...

We demonstrate porous silicon based rugate filters with 40 dB rejection first-order stopbands for longitudinal acoustic waves at hypersonic frequencies and the predicted suppression of higher order bands.
