Nicolson–Ross–Weir method - Wikipedia
http://econam.metamorphose-vi.org/index.php?option=com_content&view=article&id=134&Itemid=84 Nicolson–Ross–Weir method is a measurement technique for determination of complex permittivities and permeabilities of material samples for microwave frequencies. The method is based on insertion of a material sample with a known thickness inside a waveguide, such as a coaxial cable or a … Visa mer The method uses scattering parameters of a material sample embedded in a waveguide, namely $${\displaystyle S_{11}}$$ and $${\displaystyle S_{21}}$$, to calculate permittivity and permeability data. Visa mer In the case of low material loss, the Nicolson–Ross–Weir method is known to be unstable for sample thicknesses at integer multiples of … Visa mer • Chen, L. F.; Ong, C. K.; Neo, C.
