摘要

考虑了腔内治疗用毫米波辐照器侧表面电场分布。该辐照器由圆柱形探头侧面的平行槽组成。结果表明，电场沿狭缝方向均匀，在狭缝之外迅速减小。在穿过槽的方向上(沿着圆柱体的母线)观察到恰好在槽上方的场强峰值。为了增加辐照器方向上的场均匀性，建议增加槽的数量，如果可能的话，增加槽的宽度。

Distribution of Electrical Field Over the Lateral Surface of MW Irradiator for Intracavitary Treatment

Distribution of electrical field over the lateral surface of MW irradiator for intracavitary treatment is considered. The irradiator consists of parallel slots on the lateral surface of a cylindrical probe. It is shown that the field is uniform along the slot and rapidly decreases beyond the slot. Peaks of the field strength are observed just above the slots in the direction across the slots (along the generatrix of the cylinder). To increase the field uniformity in the direction across the irradiator it is recommended to increase the number of slots and, if possible, the slot's width.
