Nearfield probing system for anisotropic material characterization

  • Entire 12 GHz system design (concept, antennas, RF/IF system, FPGA)
  • Utilization for real-time estimation (120k measurements/s) of timber´s grain angle

Material and Component Characterization

  • Analysis of PCB materials and manufacturing technologies for applications up to 110 GHz
  • AOA Estimation for OFDM Transmission at 5.9GHz
    • Insensitive to bandwidth and center freq. deviations
    • No extensive signal processing
    • Low cost DAC, ADC, signal processing components

Scanning Microwave microscopy (SMM)

  • Based on atomic force microscopy (AFM)
  • Use conductive cantilever to inject microwave probing signal
