The use of Reverberation Chambers for testing in EMC and in other areas is likely to increase in the years to come. In this column, we have in the past paid particular attention to the technical aspects of testing in such an environment. Examples are the following Themes: Reverberation Chambers-Part I (Vol 6, Issue 1,2017, pp 63–78), Reverberation Chambers-Part II (Vol 6, Issue 2,2017, pp 76–88), and Wireless Tests in Reverberation Chambers (Vol 9, Issue 2, 2020, pp 45–55). In the current issue we report on a discussion forum which took place at EMC Europe 2020. Discussion forums, by their nature, are meant to encourage the expression of a wide range of views and stimulate debate, so in the years to come a broader, deeper, and more secure understanding of this important topic may emerge (see the discussion below).
