1 Effects at atomic and molecular level
1.1 POLARIZATION
The dielectric effect of polar molecules is known from 1912 (Debye). Polar molecules having a spatial irregularly distribution of charge and respond to an external field. Knowing the dielectric properties is particularly important for interaction of electromagnetic fild with biological systems.
To understand the nature of these effects, it is necessary to know the size of the induced field at various point inside the biological system, which implies to know the erreal part of real permittivity.
The imaginary part of permittivity gives the rate of transformation of electromagnetic energy into thermal energy.
Biological materials behave in 'terms' magnetic fild like air. Therefore, the influence of the exterrnal manetic fields is extremely low. However, it seems that there are some interactions with static magnetic fields of low frequency.
But living organisms react strongly to electric fields, with electric permittivity is much different from that of air.
Dipole moment of unit volume:
