Analytical Modelling of Power Attenuation under Parameter Fluctuations with Applications to Self-Test and Repair

Advanced sensors coupled with exponential improvements in computer technology have enabled sensors to be deployed in a wide range of applications, ranging from environmental monitoring to improved biomedical devices. However, to be useful in real-life applications - in the industrial or medical environment - a sensor has to be able to autonomously adapt in response to unusual events. The purpose of this paper is to develop a mathematical model that will enable a waveguide-based sensor - with a particular emphasis on biosensors - to autonomously implement self-test, control and repair
