| Abstract(in English) | In this paper, a shielding effectiveness (SE) is examined by finite difference time domain (FDTD) method of 3-dim under the use of a lossy material inserted into the gap instead of the conventional choke structure, as a method for suppressing a leakage waves from the gap between the main body of a microwave oven and a door. Concretely, the SE versus the variation of the gap size or the insertion length of the lossy material is examined on TE_<40> mode which is similar to the leakage wave in various higher-modes. It was found out that the SE of 30dB or more was obtained in the case that some lossy material filled up the gap. If the gap becomes 1mm, the insertion length of the lossy material of 50mm or more is necessary to obtain the SE of 30dB or more. It was confirmed quantitatively that the desired SE for practical use was obtained by using the new door seal structure. |
