Abstract
Abstract The invention comprises a technique and apparatus for destroying electro-explosive devices such as underwater mines by subjecting them to intense electromagnetic radiated fields. A unique arrangement of a capacitor which discharges into a resonant circuit including an antenna is used to generate the high energy field by pulse techniques.

Claim 1
Independent Claim
112 words
Apparatus for detonating electro-explosive devices which are susceptible to detonation by intense electromagnetic radiated fields comprising: a. a source of electrical energy; b. said source including variable capacitor means for storing said electrical energy; c. switch means in series with said variable capacitor means; d. resonant circuit means including antenna means located in the vicinity of the devices which are to be detonated; e. said resonant circuit means being connected to said source of electrical energy and said switch means by a matching network; f. said switch means being operable to discharge the stored energy in said variable capacitor means to said resonant circuit means to thereby generate pulsed intense electromagnetic fields.
