Abstract
En fremgangsmåte for å analysere et elektromagnetisk bølgefelt er gitt. Fremgangsmåten innbefatter trinnene med å måle de elektriske og magnetiske felt i det minste i en mottaker (30), og formulere et respektivt filter med hensyn til hver av gjensidige ortogonale komponenter for hver av de elektriske og magnetiske felten (33, 34) og å anvende filtrene på de målte data for å dekomponere bølgefeltet i oppovergående og nedovergående komponenter (35).
