Complex plain plot (▲) of the admittance contribution of spectrin network of suspended erythrocytes (A). Curved arrow indicates the increase in frequency from 20 kHz to 15 MHz. Arrows indicate the characteristic frequencies of βsp and γ1sp dielectric relaxations. Open triangles (Δ) indicate the model plot, Y” vs. Y’, of the complex admittance, Y*, of equivalent electric circuit (B).
