Recently, 2-D photonic bandgap reflectors in microstrip technology ha¨e been proposed. Finite-element 3-D electromagnetic simulation shows negligible ¨alues of the fields outside the central row of the periodic pattern. This suggests the use of 1-D patterns to reduce the trans¨ersal size of the refl

✦ Synopsis
In this paper, an application of microwave technology for drying or dehydrating foods with high humidity is presented. Characteristics of the microwave dryingrdehydration are discussed, and an actual processing line for a special taro, Bin-lang-yu, was developed. Our experience so far has indicated that microwave drying is feasible and suitable for drying high-humidity foods. It can also perform multiple functionalities such as cooking, drying, and sterilization, while retaining the color, smell, and flavor of the foods.
