There may be provided a method for inducing a disruption to an operation of an unmanned aerial vehicle (UAV) that communicates with a remote controller, said method may include determining to induce the disruption to the operation of the UAV; and transmitting, to the UAV, one or more disrupting commands that once executed by the at UAV causes a unit of the UAV to malfunction, the malfunction induces the disruption to the operation of the UAV.

A reusable battery-operated electromagnetic pulse (EMP) generator system comprising a pyroelectric element that accumulates high-voltage charge, immersed in a dielectric bath. A heating element heats the dielectric bath and the pyroelectric element, while a temperature sensor monitors their temperatures. The components are housed within a thermal chamber that provides insulation. A switched pulse actuator controls the rapid discharge of the accumulated charge from the pyroelectric element. The system includes a pulse shaping subsystem, a power supply unit, and a broadband radiating element such as an ultrawideband antenna for emitting the EMP. The pyroelectric element is heated and cooled to control accumulation of high voltage charge, which is discharged as an electrical pulse that is shaped and radiated as EMP.
