5. Coaxial bridges
When impedances need to be measured with very small uncertainties, or when the measurement frequency becomes high, a coaxial structure may be required. There are, however, a number of constraints that need to be taken into account. In the following, we outline the main principles and give a few examples of coaxial bridges.
5.1 The advantages of coaxial bridges and the stresses they generate
Electrical impedances store, then restore and possibly partially absorb the energy of the electric and magnetic fields generated in the vicinity of the conductors they are made up of, when these are subjected to potentials or currents that vary over time. These exchanges are intimately linked to these potentials and currents, but also depend on the spatial configuration...
