• YIG detection - DC Magnetic Field
    I'm using Hall-effect devices, very cheap, to detect the locomotives which have little magnets glued underneath on my model railway.
  • Transmission line maximum impedance
    The per-unit-length inductance can be raised with a spiral central conductor in a coax. Is that not used in some high impedance 'scope probes? Lumped-constant lines can be made whatever you want, such as distributed Y-amplifiers in old Tektronix valve oscilloscopes.
