description: Existuje nekolik metod jak merit zakladni charakteristiky bezsrazkoveho plazmatu jako je jeho hustota a teplota. Jednou z metod je porovnani spekra tepelneho sumu namereneho na antene druzice s teoretickym modelem v okoli frekvence, jejiz chovani (disperzni relace) v zavislosti na parametrech plazmatu je dobre znamo. Tato metoda byla rozpracovana pro nektere pripady mereni ve slunecnim vetru a magnetosfere mesice Io. Student se seznami s vlastni metodou a bude pracovat na jejim dalsim rozvijeni.
