Arc-shape frequency dependence of phase angle in bioimpedance spectroscopy
I have concerned myself with bioimpedance spectroscopy (BIS) from a medical standpoint for some time now, however there is one concept evading my grasp until now:
When measuring complex impedance of ...

Refractive index, wavenumber, and wave impedance of the PEC that a plane wave is normally incident on
I am trying to find the refractive index \$n_t\$, wavenumber \$k_t\$, and wave impedance \$\eta_t\$ of a perfect electric conducting medium t. Here is my work so far:
The conductivity of the PEC is \$...

Impedance of an embedded microstrip with different sub- and superstrate
I have been trying to find a formula to calculate the impedance of an embedded microstrip where the substrate has a different dielectric constant to the superstrate (so the stack up is conducting ...
