Abstract

To investigate the best frequency for a microwave reaction application, a frequency reconfigurable microwave reaction cavity based on the concept of quarter-wave coaxial cavity resonator is proposed and designed. It is able to resonate at different frequency within the bandwidth of 500~1000 MHz by only adjusting the length of the inner conductor and the depth of the feeding structure. This implies a 67% tuneable bandwidth. Within the spherical region with a radius of 50 mm surrounding the inner conductor, the effective value of electric field is greater than 2.6×10⁵ V/m for an input excitation of 500 W. As such, a frequency reconfigurable microwave reaction system can be constructed to implement a small scale experiment.
