On June 23, 2020, we gave a webinar hosted by PIKE Technologies on the main considerations when designing an ATR-SEIRAS experiment. Ian Burgess gave a 30 minute introduction to ATR-SEIRAS, including discussion of Effective Medium Theory as a framework for understanding SEIRAS as well as the key experimental consideration when designing an experiment utilizing this technique. The presentation was followed by a 30 minute question period. During the webinar, Ian provides many useful tips on how to reliably produce the notoriously challenging metal films required for the technique.
