Abstract :
A waveguide reflectometer, in combination with a fibre optic temperature probe, is used to characterise the permittivity changes of small rubber samples heated with high power microwaves. The molecular changes of rubber during vulcanisation can be clearly seen in the evolution of the measured complex dielectric constant against time and temperature
