Compact radio sources have been observed to undergo large, frequency dependent changes in intensity due to lensing by structures in the interstellarmedium, in so-called “extreme scattering events" (ESEs). While the study of astrophysical plasma lensing has primarily focused on the geometric limit of optics, coherent radio sources such as pulsars exhibit wave effects when lensed. The additional phase information provided by interference effects in the wave regime may yield more information about…
