Initiating device for an explosive charge

摘要

A device for initiating an energy-producing composition, e.g. a pyrotechnic composition or propellant charge, by means of microwaves has a microwave-sensitive receiver element containing a combination of (A) conductive material(s) and (B) material(s) which produce(s) energy or is/are able to react chemically with (A). A device for initiating an energy-producing composition such as a pyrotechnic composition or a propellant charge by means of a microwave generator has at least one receiver element which is sensitive to microwaves, placed in contact with or near to the energy composition. The receiver element contains (A) at least one conductive material in combination with (B) at least one material which produces energy or is capable of reacting chemically with (A).
