INTERACTION OF ELECTROMAGNETIC FIELD WITH BIOOBJECTS. APPLICATION OF LASERS IN BIOLOGY AND MEDICINE

Слайд 2

Описание слайда:

Four essentially varioys theraputic ways of EHF-radiation 1. Action of electromagneyic irradiation on EHF-range of freqencies which appropriate to character of fuctional disorder for adaptive precesses growth stimulation is used 2. Influence on frequencies reflection specificity of a concrete antigen 3. Influence at the frequncies that activate immune cells, but don`t activate the nonspecific cells to concrete antigen. 4. EHF-radiation action joined with factors, that distroy the irreversibly changed tissues, with infiltration in organism of activated by EHF-radiation healthy tissues

Слайд 3

Описание слайда:

The interaction of electromagnetic fields with substaces Substace in an electrical field. All bodies consist of molecules, molecule from atoms, and each atom from the positively chargednucleus and rotatinf around of it electrons, having a negative charge. Usually, bodies electrical are neutral, as with a high degree of accracy the amount of electric negative charges is equal to amount of electric field essntioally depends, how these charges are connected among themselves.

Описание слайда:

Value which shows in how many times the intensity of electric field in dielectric Eτ less than intensity of external electric field E is named as dielectric permeablility or dielectric constant έ. Thus total electric field intensity can be expressed by the following formula Value which shows in how many times the intensity of electric field in dielectric Eτ less than intensity of external electric field E is named as dielectric permeablility or dielectric constant έ. Thus total electric field intensity can be expressed by the following formula
