چکیده
ABSTRACT This paper presents a 2.45 GHz microwave cavity resonator with the novel dual function of both sensitive dielectric characterisation and directed, volumetric heating of fluids in a microfluidic chip. This method is shown to have a higher efficiency (>90 % for methanol), higher rate of heating and more accurate control than previous microfluidic microwave heating methods [1], [2]. The system is simple, robust and does not require on-chip integration of waveguide structures. Furthermore, this method can be combined with miniaturised resonators such as split rings [3] for localisation of heating within a microfluidic chip.

Microwave dielectric heating of drops in microfluidic devices.
We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent molecular dipole moment that has large dielectric loss at GHz frequencies. The relevant heat capacity of the system is a single thermally isolated picolitre-scale drop of water...
