There are many sources of data you requested. One of the best is, avaliable on Google: C.M.Alabaster: The Microwave Properties of Tissue and Other Lossy Dielectrocs, PhD Thesis, Cranfield University, UK, 2004.
Another good reference is Kapilevich, B., Litvak, B. Dtermination of Complex Permittivity.... Ariel University of Samaria, Ariel, Israel, 2010
If you are interested, I developed a microwave-noise method suitable for moving objects and irregular shapes; permittivity values were also measured by normal-incidence method. I used these methods at 4...50 GHz but any frequency can be used with real materials.
