A First Quick Tool Based on Analytical Approach for the Analysis of the Performance of Microwave Sensors in Medical Applications

In microwave medical applications, the sensor are often deployed in direct contact to human body. Under this working condition, it is hard to predict exactly the sensor behaviour and the standard methods for designing it fail. This has encouraged the use of full wave analysis for the design of the microwave sensors. However here, for sensors in waveguide technology, an approximate analytical model is derived for reflection coefficient Γ. Numerical results predicted with analytical model are in agreement with the ones performed via full wave simulations. This suggest that the proposed model can be considered as a first quick tool for design the sensor reducing the high computational cost of full wave analysis approach.
