8). It is the most liable place where microwave leakage occurs. Especially, after a long time using, the microwave leakage would enlarge at the hinge and the hook. Anyway, mechanic damage would also cause large amount of microwave leakage. Therefore, the main methods designed for preventing microwave leakage of the door are as follows:

1)Assemble a layer of steel filament or a thin metal plate with many holes at the middle of the window to made it is possible to observe the heating as well as shielding the microwave.

2)The widely used seal measurement at present is to assemble a current – resistant construct between the door and the doorframe. FIG.2-9 is the typical construction fig of the door. It was designed according to the theory of

“THETRANSFERING LINE ONE–FOURTHWAVE LENGTH IMPEDANCE CHANGER”. Although there is no connecting point from a mechanical point. It is sealed at the seam from the point of electricity, so it is called “CURRENT-RESISTANT”. Recently, with the installation of noise filter in the current resistant trough, the effect to restrain the microwave leakage (include high subharmonic) have been much improved.
