| Popis: | It has been shown recently that a properly designed Love wave sensor is very promising for (bio)chemical sensing because of its high sensitivity. Furthermore, it is well known that a Love wave has a pure shear horizontal polarization and therefore no elastic interaction with an ideal liquid. This property makes it particularly interesting for (bio)chemical sensing in a liquid environment. However, interaction with a viscous fluid can never be avoided. It causes a small frequency shift which slightly distorts the sensor response and increases the insertion loss of the device. A theoretical and experimental study of this viscous fluid loading is presented here. |
