Abstract
Oppfinnelsen angår bølgeformer for elektromagnetiske undersøkelser med styrte kilder. Bølgeformene har frekvensspektre som innbefatter tre eller flere frekvenser atskilt med hovedsakelig like avstander på en logaritmisk frekvensskala, og som spenner over en båndbredde på omkring én dekade eller mer, hvor minst tre av frekvensene har tilnærmet like samsvarende amplituder.
