Biological agent detector using a surface transverse wave resonator: preliminary report

A 500 MHz, dual-channel, surface transverse wave resonator is employed as the sensor element in a chemical/biological detector capable of operating in an aqueous environment. The purpose of this preliminary report is two-fold. First, the design of the surface transverse wave sensor and its incorporation into a man-portable detector is discussed. Second, the major problems uncovered with the initial prototype are reviewed with an emphasis on solutions that will be implemented in a second "smart" detector.<>
