<p><P>PROBLEM TO BE SOLVED: To provide a probe sensor of a compact device for remotely detecting the presence of chemical or biological agents through the use of an electromagnetic microcavity element or an array or assembly of microcavity elements. <P>SOLUTION: The sensor is provided with electromagnetic microcavities. An agent to be detected passes through the microcavities and is adsorbed and/or absorbed by the microcavities to modify the electromagnetic field inside the microcavities. After the agent has been adsorbed and/or absorbed, a probe beam is applied to the microcavities. The change of electromagnetic field is detected by a detector, and the frequency of the probe beam at which the resonance is observed is indicative of a particular agent being present. A method for detecting chemical and/or biological compounds uses the sensor. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
