  • Publication number: 20210376926
    Abstract: A direct-detection optical data receiver capable of low-latency SSBI cancellation using one or more FIR filters in the chain of digital signal processing thereof. In an example embodiment, a DSP of the receiver may have first and second serially connected FIR filters whose filter coefficients are updated based on a same feedback signal. An SSBI-cancellation circuit of the DSP is configured to estimate the SSBI by summing a scaled square of the filtered signal generated by the first FIR filter and a scaled square of the filtered signal generated by the second FIR filter. In some embodiments, the SSBI-cancellation circuit may have two or more serially connected stages, each of which incrementally improves the accuracy of the SSBI estimate. In some embodiments, the need for dedicated and/or specialized filter-calibration procedures may beneficially be circumvented.

  • Publication number: 20210373123
    Abstract: Determining a target's range profiles is an important issue for coastal surveillance radars because it can give us the knowledge about the target, for example, target's type, target's structure and its length along radial direction. Some modern radars nowaday are equipped with the feature of target's range profile extraction, but the results are not accurate due to limitations in processing algorithms. The invention “system and method of determining target's range profiles for coastal surveillance radars” solves the above problem in the direction of proposing a system of technical solutions and associated algorithm improvements.

  • Patent number: 11092661
    Abstract: A ferromagnetic resonance (FMR) measurement system is disclosed with a waveguide transmission line (WGTL) connected at both ends to a mounting plate having an opening through which the WGTL is suspended. While the WGTL bottom surface contacts a portion of magnetic film on a whole wafer, a plurality of microwave frequencies is sequentially transmitted through the WGTL. Simultaneously, a magnetic field is applied to the contacted region thereby causing a FMR condition in the magnetic film. After RF output is transmitted through or reflected from the WGTL to a RF detector and converted to a voltage signal, effective anisotropy field, linewidth, damping coefficient, and/or inhomogeneous broadening are determined based on magnetic field intensity, microwave frequency and voltage output. A plurality of measurements is performed by controllably moving the WGTL or wafer and repeating the simultaneous application of microwave frequencies and magnetic field at additional preprogrammed locations on the magnetic film.

  • Publication number: 20210025958
    Abstract: A ferromagnetic resonance (FMR) measurement method is disclosed wherein a magnetic film or stack of layers is patterned into elongated structures having a length along a long axis. A magnetic field (H) is applied in two different orientations with respect to the long axis (in-plane parallel and perpendicular to the long axis) or one orientation may be perpendicular-to-plane. In another embodiment, H is applied parallel to a first set of elongated structures with a long axis in the x-axis direction, and perpendicular to a second set of elongated structures with a long axis in the y-axis direction. From the difference in measured resonance frequency (?fr) (for a fixed magnetic field and sweeping through a range of frequencies) or the difference in measured resonance field (?Hr) (for a fixed microwave frequency and sweeping through a range of magnetic field amplitudes), magnetic saturation Ms is determined using formulas of demagnetizing factors.

  • Publication number: 20200393525
    Abstract: A scanning ferromagnetic resonance (FMR) measurement system is disclosed with a radio frequency (RF) probe and one or two magnetic poles mounted on a holder plate and enable a perpendicular-to-plane or in-plane magnetic field, respectively, at test locations. While the RF probe tip contacts a magnetic film on a whole wafer under test (WUT), a plurality of microwave frequencies (fR) is sequentially transmitted through the probe tip. Simultaneously, a magnetic field (HR) is applied to the contacted region thereby causing a FMR condition in the magnetic film for each pair of (HR, fR) values. RF output signals are transmitted through or reflected from the magnetic film to a RF diode and converted to voltage signals which a controller uses to determine effective anisotropy field, linewidth, damping coefficient, and/or inhomogeneous broadening for a sub-mm area. The WUT is moved to preprogrammed locations to enable multiple FMR measurements at each test location.

  • Publication number: 20200386840
    Abstract: A ferromagnetic resonance (FMR) measurement system is disclosed with a plurality of “m” RF probes and one or more magnetic assemblies to enable a perpendicular-to-plane or in-plane magnetic field (Hap) to be applied simultaneously with a sequence of microwave frequencies (fR) at a plurality of “m” test locations on a magnetic film formed on a whole wafer under test (WUT). A FMR condition occurs in the magnetic film (stack of unpatterned layers or patterned structure) for each pair of (Hap, fR) values. RF input signals are distributed to the RF probes using RF power distribution or routing devices. RF output signals are transmitted through or reflected from the magnetic film to a plurality of “n” RF diodes where 1?n?m, and converted to voltage signals which a controller uses to determine effective anisotropy field, linewidth, damping coefficient, and/or inhomogeneous broadening at the predetermined test locations.

  • Patent number: 10833769
    Abstract: A PDM-capable coherent optical receiver can be implemented using four high-bandwidth photodiodes connected in a single-ended electrical configuration. The SSBI present in the electrical output of the single-ended photodiodes is effectively canceled in the receiver DSP based on measurements of average optical power of the optical data and local-oscillator signals. In various embodiments, such measurements can be performed using relatively inexpensive circuits/components incorporated into the optical front end of the receiver. For a given signaling interval, the DSP runs an iterative algorithm to compute estimates of the in-phase and quadrature components of the optical data signal and achieve a level of performance comparable to that of a coherent optical receiver having a greater number of high-bandwidth photodiodes connected to form balanced photodetectors. The achieved reduction in the number of high-bandwidth photodiodes can advantageously be used, e.g.
