The number of current applications in the THz-frequency range (0.1–10 THz), e.g. full-body scanners or WLAN communication technologies, is rapidly rising. Accordingly, the need for methods to determine the risk for the general public and for employees due to electromagnetic exposure from such sources is growing. The currently available literature provides only information about dielectric material...
In 2011 IEC-CISPR-B2 decided to start a project to investigate the possibility of introducing two new measurement distances (3 m and 5 m)1 in CISPR 11 [1] for radiated emission measurements on medium sized test objects (devices under test) in the frequency range 30 MHz–1 GHz. In this context ‘medium sized’ test objects are objects that fit within an imaginary cylindrical test volume of 3 m diameter...
In this paper, on approach, which describes the electromagnetic (EM) field coupling with a transmission line (TL) located in a closed rectangular enclosure, has been developed. The metallic enclosure will be assumed ideal (perfectly conducting walls), excited by internal source. The calculation of the EM field generated inside the box is based on previous published work [1]. Our approach consist on...
Radiated emission testing of electric components, modules and systems is mandatory. Such tests are performed in absorber-lined shielded enclosures during the development process. Due to strict time schedules, limited access to EMC measurement facilities and cost reasons, alternative methods are needed. This contribution presents an approach for a pre-compliance test method for radiated emissions of...
