    Abstract: A coaxial transmission line, e.g. a coaxial cable, includes an inner electrical conductor, an outer electrical conductor, a dielectric region between the inner electrical conductor and the outer electrical conductor, and an electrically thin resistive layer within the dielectric region and concentric with the inner electrical conductor and the outer electrical conductor. The electrically thin resistive layer is a resistive layer configured to be transparent to a subtantially transverse-electromagnetic (TEM) mode of transmission, while absorbing higher order modes of transmission.

    Abstract: A probe includes a main electro-optical modulator (130), first (150) and second (160) optical couplers each having a respective input (152, 162), through (154, 164) and isolated (156, 166) port, and reference (170) and test (174) optical detectors. Reference light and test light, respectively, are received at the inputs (152, 162) of the optical couplers (150, 160). Main electro-optical modulator 130 includes an RF through-line (136) between input (132) and output (134) RF connectors, and a modulator optical path (138) alongside the RF through-line. The first and second optical couplers couple the reference and test light to opposite ends of the modulator optical path. The reference and test optical detectors are coupled to the second and first isolated ports (166, 156), respectively, to generate reference and test IF signals respectively representing forward and reverse RF signal propagation along the RF through-line. The received reference and test light is modulated at an LO frequency, or an auxiliary electro-optical modulator (180) is provided to modulate unmodulated received light.

    Abstract: Electro-optic (EO) modulators are disclosed. The EO modulators include a substrate and an EO material layer disposed over the substrate. The EO material layer and the substrate provide an optical waveguide having an optical group velocity (OGV). The EO modulators also include electrodes disposed over the EO material layer to provide a coplanar waveguide (CPW). The CPW has a radio-frequency (RF) phase velocity, and the electrodes have a gap therebetween. The EO modulators also include a superstrate disposed over the EO material layer and configured to be raised and lowered, or disposed and removed to tune the RF phase velocity to be substantially the same as the OGV, wherein a space exists between the superstrate and the EO material.

    Abstract: An apparatus is for generating an emulated radar reflection signal of a target. The apparatus includes a radar detector configured to detect a radar signal frame emitted by a device under test (DUT), an emulation transmitter configured to generate an emulated radar reflection signal of a target being emulated, and a processor configured to generate control signals which control the emulation transmitter according to at least one characteristic of the target being emulated. The processor is further configured to determine a current radar parameter among plural possible radar parameters of the radar signal frame of the DUT, and to adapt the control signals which control the emulation transmitter according to the determined current radar parameter of the radar signal frame of the DUT.

    Abstract: A device for detecting and selectively reflecting an incident microwave signal or millimeter-wave signal is disclosed. The device includes a plurality of antennae disposed in an array; and a diode disposed at each input of each antenna, each diode having an input adapted to selectively receive a reverse bias signal, or a zero bias signal, or a forward bias signal. The device also includes a switching device connected to each input, and configured to selectively apply the forward bias signal, or the reverse bias signal or the zero bias signal to each of the diodes. In forward bias, each of the plurality of antennae reflects the incident microwave signal or millimeter wave signal; and in zero bias or reverse bias each of the plurality of antennae detects the incident microwave signal or millimeter wave signal.
