Photonic and phononic crystals and metamaterials appreciate an increasing interest as new sensor principle. Photonic crystal sensors are further developed whereas phononic crystal sensor applications have just appeared at the horizon.
The fundamental principle is based on propagation of acoustic or electromagnetic waves through a composite material. The periodic arrangement of the constituents allows for tailoring the acoustic or optical properties of the sensor, thereby overcoming limitations of natural materials. Up to now phononic and photonic crystals and metamaterials is a strong domain of physics due to unexpected physical effects like negative (effective) mass, density or negative refractive index.
It seems to be obvious that such devices can be turned into a sensor if the geometry alters due to an external force or if material properties if one of the constituents of a photonic or phononic crystal change. Especially the latter gives access to liquid chemical or biosensors overcoming the limitations of classical sensor principles.
The Special Session is about bringing phononic and photonic crystals as well as metamaterials to the attention of the sensor community. Interaction should be effectively established with researches knowing the application needs and researchers working in sensor technology area.

Organizer: Ralf Lucklum, Otto-von-Guericke-University Magdeburg, Germany,

Ralf Lucklum has been employed at the Otto-von-Guericke University, Magdeburg (Germany) at the Department of Electrical Engineering since 1986. In 1977 he received his Ph.D. degree; in 2002 he habilitated at the Institute of Micro and Sensor Systems and is currently chairing the Sensor and Measurement Science group. He has been involved in several national and international sensor research projects. His present research activities include the development of acoustic microsensors ultrasonic sensor systems and phononic crystal sensors for chemical analysis and material science as well as application orientated sensor projects like for process monitoring in fluidic systems.
