Chemical/biological contaminant detector for aqueous environments: preliminary report

Paired surface transverse wave resonators operating near 500 MHz are being used as the sensing element in a chemical/biological detector capable of operating in water. Initially, the design of the surface transverse wave detector is discussed. Then, the major problems uncovered with the prototype detector are reviewed with an emphasis on solutions to these problems that will be implemented in a second-generation "smart" detector.<
