PROJECT TITLE :
Adaptive Coupling of Resonators for Efficient Microwave Heating of Microfluidic Systems
An electronically adaptive coupling technique is presented for a microwave microstrip resonator to enhance the efficiency of liquid heating in a microfluidic system. The concept relies on feeding the resonator with 2 synchronized inputs that have a variable phase shift between them. A Wilkinson power divider and section shifter were designed and fabricated for this purpose. Both simulation and measurement (using chloroform as an exemplar liquid) demonstrated that the adaptive coupling can be used to optimize the heating efficiency of the liquid.
