Uniformity of electric field intensity of microwaves within the microwave oven cavity is necessary to ensure even load-heating, and is particularly important in pathology procedures where small volume irradiation is carried out. A simple and rapid method for mapping electric field distribution, using reversible thermographic paint, is described. Spatial heating patterns for various positions, and the effects of introducing dummy loads to modify heating distributions, have been obtained for a dedicated microwave processor, and comparison made with a domestic microwave oven.
微波炉腔内微波电场强度的均匀性对于确保负载均匀受热是必要的，这在进行小体积辐照的病理程序中尤为重要。本文描述了一种使用可逆热成像涂料绘制电场分布的简单快速方法。对于一台专用微波处理器，已获得不同位置的空间加热模式以及引入虚拟负载以改变加热分布的效果，并与家用微波炉进行了比较。
