Dr. Akhlesh Lakhtakia, Charles Godfrey Binder Professor in Engineering Science and Mechanics, was recently highlighted on Penn State Live with his work entitled “Sculptured materials allow multiple channel plasmonic sensors.”

Sensors, communications devices and imaging equipment that use a prism and a special form of light – a surface plasmon-polariton – may incorporate multiple channels of redundant applications if manufacturers use sculptured thin films. Surface plasmon resonance devices currently have a wide range of applications. They are commercially used as sensors for humidity, temperature, chemical concentrations and chemical composition. SPR devices can be used in a form of surface microscopy, as wave guides and tunable filters. Creating two or more channels in each device would multiply SPR utility in all areas of application.
