Abstract:
1. An apparatus for shielding electromagnetic wave of an oven door comprising: a choke means including a choke base formed with an inner portion of the oven door, a choke inner side portion bent perpendicularly from the choke base and a choke top bent from the choke inner side portion to form a front circumferential portion of an oven cavity; and a plurality of slots formed in the choke top and the choke inner side portion at a predetermined interval, each of the slots being extended from a distal end of the choke top to a predetermined point of the choke inner side portion, the predetermined point being distanced the same as or smaller than the half of the width of the choke inner side portion from a joint between the choke top and the choke inner side portion, whereby electromagnetic waves having various modes of incidence angles are shielded from leaking out of the cavity.
