Can permittivity be imaginary?
For an ideal dielectric material, ε is a real number, but in practice for any dielectric material, there is also an imaginary component that is associated with the dielectric loss because of the poor conductivity of the material. Therefore, ε is called the absolute complex permittivity, which is also denoted by ε* and describes the total interaction of the dielectric materials with the variable electrical field.
How to Calculate Power Loss Density?
Power Loss Density calculator uses Power Density = Frequency*Complex Relative Permittivity*8.85418782*10^-12*Electric Field Strength^2 to calculate the Power Density, The Power Loss Density formula shows that the amount of reaction substances affects power dissipation during the reaction process. Power Density is denoted by Pd symbol.
How to calculate Power Loss Density using this online calculator? To use this online calculator for Power Loss Density, enter Frequency (f), Complex Relative Permittivity (εr″) & Electric Field Strength (F) and hit the calculate button. Here is how the Power Loss Density calculation can be explained with given input values -> 0.013813 = 5000000*0.78*8.85418782*10^-12*20^2.
