Over the last few years, the interest in vibrating intrinsic reverberation chambers (the so-called VIRCs) among both industrial and academic communities has been growing rapidly. These low-cost and movable chambers are increasingly perceived as a reverberation chamber offering different possibilities and potential compared to 'traditional' parallelepipedic ones, rather than merely another kind of reverberation chamber.
Therefore, the time has come this year in Paris for the VIRC to stand on their own and organize the first workshop dedicated solely to this topic during an EMC Europe symposium!
This half-day workshop will bring together:
- A presentation on the genesis and history of VIRC by its inventor, Mr. Frank Leferink
- Technical presentations showcasing recent advances in VIRC
- Hands-on, demo, and interactive sessions with a small VIRC prototype
Analysis of the Field Homogeneity and Isotropy in a Tent-Like Reverberation Chamber - Comparison of Using a Rotating Stirrer and Shaking the Walls
Otto-von-Guericke-Universität Magdeburg, Germany
We validated a tent-like reverberation chamber equipped with a rotating mode stirrer and tested the empty and maximum loaded chamber, but found a very poor behaviour in this case with a strong anisotropic field. Therefore, we tried several methods to improve the field uniformity, such as manually shaking the wall or changing the polarization of the TX antenna.
Anechoic measurements within a fully-stirred VIRC
XLIM laboratory, University of Limoges, France
This presentation will introduce the principle of “anechoic-like” measurements (antenna radiation pattern and radar cross section) performed in a VIRC where the stirring process is excellent. This has the effect to cancel the appearance of any unstirred path. Therefore, the line-of-sight (i.e. the path we want to measure) is the unique invariant path within the VIRC and can then be easily extracted.
Dual VIRC for shielding effectiveness measurements
1University of Twente, Enschede, The Netherlands; 2Thales Nederland BV, Hengelo, The Netherlands
What’s better than a VIRC? A Dual VIRC!
Building on the concept of nested reverberation chambers, the Dual VIRC setup combines two similarly sized chambers to optimize shielding effectiveness measurements. This talk will highlight the unique advantages of the Dual VIRC and discuss them in both theory and practice.
