Abstract: A method includes receiving electromagnetic signals containing pulses. The method also includes converting the pulses contained in the electromagnetic signals into an electrical signal that identifies at least some of leading or trailing edges of the pulses. The method further includes repeatedly (i) accumulating the electrical signal to generate a voltage using an integrating circuit and (ii) resetting the integrating circuit in response to the voltage of the integrating circuit meeting or exceeding a threshold voltage. In addition, the method includes providing a count value identifying a number of times that the voltage of the integrating circuit meets or exceeds the threshold voltage. Each time the voltage of the integrating circuit meets or exceeds the threshold voltage is representative of a specific number of pulses received in the electromagnetic signals.

Abstract: An apparatus includes an isolation barrier configured to absorb electromagnetic energy. The isolation barrier includes multiple layers stacked on one another. Each of the multiple layers includes at least one dielectric material, at least one thin-film resistive material carried by the at least one dielectric material, and conductive strips in electrical contact with the at least one thin-film resistive material. The isolation barrier also includes vias through the multiple layers. Multiple ones of the vias are positioned along each of the conductive strips, and the vias electrically couple the conductive strips in the multiple layers to one another. The isolation barrier is configured to guide the electromagnetic energy through the multiple layers to enable absorption of the electromagnetic energy by the at least one thin-film resistive material.

Abstract: An apparatus includes a capsule configured to be launched or carried towards an unmanned aerial vehicle (UAV). The apparatus also includes a directed energy device within or carried by the capsule. The directed energy device includes a first inductor configured to generate an inductive magnetic field that is able to inductively couple into one or more electronics of the UAV in order to disable or destabilize the UAV. The capsule can be configured to be launched towards the UAV and can include a loiter mechanism (such as a rotor, umbrella, or parachute) configured to maintain a position of the capsule or to slow a descent of the capsule after launch. The capsule can also be configured to be carried towards the UAV by a different UAV, and the apparatus can further include a tether coupling the capsule to the different UAV.

Abstract: A low-loss millimeter-wave radome is provided. The low-loss millimeter wave radome includes a perforated and plated metallic plate and a low-loss dielectric encapsulation material to encapsulate the perforated and plated metallic plate. The perforated and plated metallic plate includes multiple metallic sheets and electrically conductive plating. The multiple metallic sheets respectively define a periodic array of sub-wavelength holes and are laminated together such that the periodic array of sub-wavelength holes combines into a periodic array of perforations.

Abstract: In one aspect, a Y-splitter includes a first arm having a first port, a second arm having a second port, a third arm having a third port, a fourth arm having a fourth port and a Y-split portion having a first end coupled to the first arm, a second end coupled to the second arm, a third end coupled to the third arm and a fourth end coupled to the fourth arm. The Y-split portion splits a signal from a first signal path from the first port into a second signal on a second signal path and a third signal on a third signal path. A first angle between the second signal path and the first signal path is greater than 90 degrees and a second angle between the third signal path and the first signal path is greater than 90 degrees.

Abstract: An impedance matching power combining/dividing system and a method for combining power combiners/dividers are presented. The impedance matching power combiner comprises a cylindrical matching cavity, two or more coaxial inputs, each of the two or more coaxial inputs having an inner input conductor and an outer input conductor and having a source impedance, a coaxial output having an inner output conductor and an outer output conductor and having a load impedance and a circular matching plate suspended inside the cylindrical matching cavity, wherein the inner input conductors and the inner output conductor are electrically connected to the matching plate, the outer input conductors and the outer output conductor are electrically connected to the cylindrical matching cavity and the cylindrical matching cavity at least partially matches the source impedance with the load impedance. The system and method to combine/divide groups of power combiners/dividers to handle high power are also presented. The power combiners/dividers have a small transverse dimension that they easily fit in a phased array lattice structure and operate at high frequencies.

Abstract: A system for triggering improvised explosive devices (IEDs) with an alternating magnetic field. In one embodiment, the magnetic field is produced by a magnetic field projector in the shape of one-half of a torus, the half-torus being composed of several conductive segments referred to as toroidal wedges. A poloidal current flows in each toroidal wedge, producing a magnetic field that is projected by the half-torus. The magnetic field may induce a current, producing heating, in a conductive loop in an IED and triggering the IED.

Abstract: A wavefront transformer for reflecting and transforming an incident electromagnetic wavefront includes an electrically-conductive substrate with spaced perforations (cavities), which may have uniform spacing and varying depth. The perforations may have a radius that is close to and greater than a cutoff radius for one or more intended incident frequencies of the incident wavefront. The spaced perforations may be filled with air or may be filled with a dielectric solid material. The substrate may be covered with a cover made of a dielectric solid material. The transformer may be made by drilling holes in the substrate. Alternatively a plate having protrusions on it corresponding to the desired perforations may be used to form the perforations on the substrate. The plate may be removed or left in place after the formation of the perforations.
