vimeo.com/1030103688 Here is the link for my talk. Although I had some technical problems with my tablet, many positive discussions made me feel interested in the topic. I also thank Prof. Costas Sarris for the organization.


I will give a webinar on SAM and OAM of EM waves at Friday, Nov. 15, 9:30 AM EST. utoronto.zoom.us/j/81199606349
