Test Fixtures for RF Susceptibility Testing

The most likely standard test fixture for RF susceptibility testing is the twin-strip transmission line, or its half-space counterpart. Its capacitance per meter (length) is 2? or 4?; characteristic impedance Zc= Z0/2 or Z0/4; voltage gradient Ez = V/w or 2 V/w; magnetic field Hy = V/w Z0 or 2 V/w Z0, respectively.
