High Power related issues such as Multipactor, Corona breakdown and Passive Intermodulation (PIM) are common effect frequently observed in passive microwave components especially filters, where excessive storage of RF energy supports such undesired phenomena. Present and near future microwave systems must support higher power levels, as well as an increased degree of components integration, thus widening the risk of high power issues. This workshop will focus on those subjects and aim to enhance the understanding of the phenomena and especially remedies in order save design cycle times and costs to manufacturing industries of microwave filters and passive equipment. The workshop will also help researches, designers, test engineers and users of any high power RF hardware to exchange ideas. Another important area to be covered in the workshop is the standardization & harmonization and co-ordination of efforts to mitigate these topics.
