A new device designed by the senior author of the current paper was examined and tested in the Materials Research Laboratory of The Pennsylvania State University. The device consists of an unconventionally driven magnetron whose directional output is conditioned by filters and a tailored horn antenna. Although the origin of the radiation is an ordinary 600 W magnetron, the modified radiation is not contained by either a Faraday cage or by microwave shielding. It interrupts the operation of electronic devices, shutting them off without apparent harm to the circuitry. The radiation was observed to pass through or circumvent a one inch block of aluminium. Lastly, it unexpectedly attenuated in the building ventilation ducts which were completely outside of the directional field, resulting in the heating of and off-gassing from sealant in the duct flanges.
