The cascades produce pair plasma bunch discharges in quasi-periodic spark events. The cascade properties, and therefore also the coherent radiation, depend strongly on the magnetospheric plasma properties and vary significantly across and along the polar cap. Importantly, where the radio emission emanates from in the polar cap region is still uncertain.\n  We investigate the generation of electromagnetic waves by pair cascades and their propagat","authors_text":"Andrey Timokhin, Axel Jessner, Jan Ben\\'a\\v{c}ek, J\\\"org B\\\"uchner, Martin Pohl, Patricio A.
