| 摘要 |
There is disclosed a microwave heating device (1) in which microwave energy from a magnetron (2) is directed into a multi-mode cavity by way of one or more dielectric resonator antennas (8) disposed at a periphery of the cavity. Additional microwave sensors (9), which may also be configured as dielectric resonator antennas (8), may also be provided at the periphery. By using appropriate feedback and control circuitry, food (7) or other items may be heated in the cavity according to a predetermined heating profile and without the need for mode stirrers or other moving parts. |
