Thermal biological effects of microwave can denature the protein.The time causing this effect is determined by the irradiation power density of the high power microwave,so the measurement of the power density is the base of study on microwave biological effects.Using the dielectric properties of the water-paper mixture material such as complex permittivity,reflection coefficient on air interface,attenuation coefficient and water evaporation mass,the incident power density can be obtained.
