The nonmetallic structure is scanned with an electromagnetic pulse in the range of 200 GHz to 4 THz. The electromagnetic pulse includes a plurality of frequencies within the Terahertz range and is not restricted to a single designated frequency. The frequency range is sensitive to changes in impedances and refractive index within the structure. After the electromagnetic pulse passes through the nonmetallic structure, it may be evaluated for changes in impedance in the nonmetallic structure at different locations, and, when present, whether the changes in impedance impact the ability of the structure to perform the function for which it was designed.

  • Patent number: 9924873
    Abstract: An electromagnetic tomography system for gathering measurement data pertaining to a human head includes an image chamber unit, a control system, and a housing. The image chamber unit includes an antenna assembly defining a horizontally-oriented imaging chamber and including an array of antennas arranged around the imaging chamber. The antennas include at least some transmitting antennas and some receiving antennas. The control system causes the transmitting antennas to transmit a low power electromagnetic field that is received by the receiving antennas after passing through a patient's head in the imaging chamber. A data tensor is produced that may be inversed to reconstruct a 3D distribution of dielectric properties within the head and to create an image. The housing at least partially contains the antenna assembly and has a front entry opening into the imaging chamber. The head is inserted horizontally through the front entry opening and into the imaging chamber.

  • Patent number: 9857410
    Abstract: A harmonic load pull system uses a number of synchronized signal sources to inject harmonic power into the output of a power transistor. The mismatch between the signal sources and the transistor internal impedance is reduced by using multi-harmonic tuners, which pre-match the impedance of the signal sources to the internal impedance of the transistor at each harmonic frequency independently. Actual tuning is electronic by changing the amplitude and phase of the injected signals. The transmitted and reflected waves are measured and optimized through bi-directional couplers connected between the transistor and the tuner and a wideband harmonic receiver.

  • Patent number: 9835652
    Abstract: A multi-frequency programmable and remotely controllable variable attenuator and phase shifter (MF-VAPS) network utilizes wideband three port circulators, power combiners, high-low pass filters and a calibrated multi-harmonic tuner to control the amplitude and phase of the transmission factor (A21) at up to three user defined frequencies individually. The harmonic signal components are divided in frequency bands and injected into the circulator's port 1 and extracted from port 3, whereas the tuner is connected to port 2 and terminated with Zo. When the tuner is initialized (S11=0) the transmission factor of the network is zero; when the tuner is at maximum reflection at any frequency the transmission factor is also maximum. Changing the reflection phase of the tuner controls the transmission phase <A21 by the same amount, up to 360°.

  • Patent number: 9810646
    Abstract: Disclosed is an improved system and method to treat an edge of a material for determining a property of such material through measurements of electromagnetic waves. The system and method are operative to mitigate the adverse effects caused by the interaction between an electromagnetic wave and an edge of a sample of a material under test. The system and method define a configuration to block and significantly attenuate the propagation of electromagnetic waves that may reach an edge of the sample being evaluated. This configuration reduces the undesired effects caused by edge-diffraction that may interfere with the measurement of desired electromagnetic waves for material evaluation. As a result, a property of a material under test can be measured more accurately, especially near the edges of such material. In addition, the system and method enable the evaluation of a small-size sample of a material.

  • Patent number: 9733289
    Abstract: A reflectometer for use in measuring scattering (S-)parameters for a device under test (DUT) includes a test port, a radio frequency (RF) output signal source, and a local oscillator (LO) signal. The LO signal is used to downconvert the RF output signal to an incident IF signal. The reflectometer is useable as a first reflectometer with a second reflectometer such that the first and second reflectometers are phase synchronized by a synchronization signal. Phase and magnitude of transmission S-parameters of the DUT are measurable when the first reflectometer is used with the second reflectometer. The roles of the first and second reflectometers are reversible to allow for measurement of forward and reverse parameters. Further, the synchronization signal can be provided by one reflectometer to the other (or both can receive a separately generated synchronization signal) via a wire or fiber optic cable, for example, or via a wireless connection.

  • Patent number: 9730633
    Abstract: Immediately after airway placement and/or following any patient transfer, an automated program may be activated in a CO2 monitoring device to provide an airway device placement check. The automated program needs time to determine if the airway placement has been successful or not. During analysis of CO2 respiration data by the program, real-time feedback is displayed to the user as soon as the airway check program is activated until the time that a final decision on the success of airway placement is made. The real-time feedback displays one or more indicators of the progress of the program toward a determination of a successful or failed placement.
