Typically, on-wafer measurements of microstrip based MMICs require via holes as ground contacts. To avoid these, the design of ground contacts for on-wafer probing at mmwave frequencies using eletromagnetic field coupling is presented in this paper. Theoretical and experimental results of the respective transitions are given as well as a test deembedding this transition from the behaviour of a transmission line.

Neutron scattering experiments on carbon tetrafluoride (CF4) at high pressure were performed along the 370 K isotherm at three supercritical densities, covering a density range from ρ=1.07 to 1.26 g cm−3. The structure factors of the investigated thermodynamic states and the weighted sums of the atom pair correlation functions are presented. The variation of the density has only a weak effect on the structure factors. The experimentally obtained total atom pair correlation functions are interpreted with reverse Monte Carlo simulations. The atom pair correlation functions and angular distribution functions indicate a completely disordered arrangement of the molecules in fluid CF4 with no significant short-range orientational order, except for very close distances.
