My bet is that the disruption of the penetrating jet is done by generating a powerful magnetic field on the detection of an incoming missile. Probably using a plain single-pulse RADAR. The jet is a nice conductive plasma moving very fast, which means that large eddy currents can be induced in it and a lot of force created merely by the jet flowing through the magnetic field - either bending or expanding the jet and causing it to break up. The "high voltage" would be the capacitors holding the energy required for the field and the coils generating the field could be wide copper tracks etched onto Mylar PWB film and then glued to a Titanium protective shield - Titanium is a poor conductor and nonmagnetic so it would not interfere much with the field. Stainless steel could be used also, if one was cheap, with more losses. Of course the energy storage could do more "shots" than one and the coils will not heat up either because the duty-cycle will be very low - thousands of amps for a couple of ms once in awhile. The pulses would not be particularly dangerous to infantry or electronics - military electronics is EMP hardened anyway and no infantryman uses a pacemaker... I think it is a very neat idea.
