1. An automated resonant waveguide cavity system for determining one or more complex permittivity measurements of a sample, the automated resonant waveguide cavity system comprising:
a resonant cavity;
a waveguide coupled to the resonant cavity;
a programmable network analyzer (PNA) coupled to the waveguide;
a computing device comprising at least one memory storing processor executable code for a determination engine and at least one processor executing the processor executable code to cause the determination engine to:
obtain data from the PNA, the data being respective to the sample within the resonant cavity, and
integrate a plurality of analytical and modeling functions in determining the one or more complex permittivity values of the sample from the data.
