The simulation of the microwave shielding properties of the dual band pass frequency selective surface

Without proper caution, the microwave leakage from a microwave oven door can be harmful to users' health. In practice, the leaked radiation has to be blocked while the visible light is allowed to pass for a visual inspection of the cooking progress inside the oven. To fulfil the requirements, t...

In practice, the leaked radiation has to be blocked while the visible light is allowed to pass for a visual inspection of the cooking progress inside the oven.
