Tables of dielectric materials: what is a modern update for Von Hippel's 1954 tables?

I have been working for a long time with the dielectric dataset at the Arthur R. Von Hippel's book "Dielectric Materials and Applications" (1954, reprinted in 1966). I am looking for related...

What are the biological hazards (and regulations) of electromagnetic radiation at 100Hz-100kHz ?

I am investigating the biological hazards (and regulations) of electromagnetic radiation close and at LF band (e.g., 100Hz-100kHz). Any literature suggestion?

How to design an electrode blocking scheme for dielectric spectroscopy?

My broadband dielectric spectroscopy (BDS) studies are mainly associated to soil samples. Nonetheless, any comment for other materials is welcome. It is well known that, when dealing with low...

How does current density impact on electrode polarization effects in low-frequency imp. spectroscopy?

Usually we find at the spectroscopy literature the following concept: the electrode surface area is strongly associated with the electrode polarization (EP) effects, i.e., a smaller surface area...

Do you know about any study that highlights the aspect "distance between the potential probes" in 4-electrode (tetrapolar) impedance measurements?

The electrode polarization (EP) effects can still be observed in 4E/4T (electrodes/terminals) systems even when platinization and similar methods to increase the surface area of the electrodes are...
