1. A screening device, comprising:
- a first antenna configured to transmit a first microwave to a human body to generate a second microwave and a third microwave, the second microwave being generated by a diffraction of the first microwave at the human body, the third microwave being a part of the first microwave passing through the human body; and
a second antenna configured to receive the second microwave in a first period and to receive the third microwave in a second period,the screening device screening an interior of the human body by detecting the third microwave, andthe screening device screening a surface of the human body by detecting the second microwave.
