中文摘要 | 微波爐是科技文明的產品,若因使用不當或老舊發生電磁波外洩,居家環境會暴露於電磁輻射領域中而產生電磁環境污染問題。本研究旨在降低微波爐所引起的電磁環境污染問題,提出微波爐用頻率2.45GHz的電磁波吸收之解決對策並詳述電磁波吸收的設計方法。本論文中分析出電磁波吸收性能與材料厚度及複數介電係數有互相依存之關係。選擇吸收材料的厚度爲d=0.62cm且複數介電係數的值爲ε(下標 r)=24.9-j6.1或選擇吸收材料的厚度爲d=1.23cm且複數介電係數的值爲ε(下標 r)=6.7-j3.0時,均可在微波爐用頻率2.45GHz處得到30dB以上的電磁波吸收性能之反射衰減量。 |
英文摘要 | The microwave oven is the products of the scientific and technological civilization. When electromagnetic wave leakage is produced in virtue of unsuitable use or dilapidated condition, the question for electromagnetic environmental pollution of the house can produced by electromagnetic radiation arose from the microwave oven. The purpose of this research tried to reduce the electromagnetic environment pollution arose from the microwave oven. Also, this research proposed that the building material near the microwave oven offer the settlement countermeasure of electromagnetic wave absorption and explain the design method of electromagnetic wave absorption. This paper analyzed that electromagnetic wave absorbing performances depend on the suitable thickness and complex permittivity of material. When the complex permittivity and the thickness of material are chosen as ε(subscript r)=24.9-j6.1 and d=0.62cm or ε(subscript r)=6.7-j3.0 and d=1.23cm, electromagnetic wave absorbing performances obtained return loss above 30dB at 2.45GHz for the microwave oven use. |
