Skin Depth Calculator

The Skin Depth Calculator determines the Skin Depth for a metal at a defined frequency (f), which is one of the most useful tools that an engineer can use to determine the minimum thickness of any metal to be used at a defined frequency to minimize the loss in a transmission line or resonant circuit.  The Skin Depth formula shown below is valid at frequencies away from strong atomic or molecular resonances.

The Skin Depth Calculator is Frequency and Conductivity dependent:

  1. 1INPUT Frequency.
  2. 2SELECT Metal Conductivity from list of 10 metals, or type in a USER DEFINED Conductivity.
  3. 3OUTPUT – Skin Depth is Calculated in microns (um).

Finally, SiberSci, LLC also provides visitors with access to Electromagnetic Engineering Calculators that are used for designing circuits, or exploring solutions to problems.  Three transmission line calculators are provided that include a Coax TEM Mode Calculator, a Rectangular Waveguide TEm,n Calculator, and to complete this set a Rectangular Waveguide TMm,n Calculator.  The remaining three Electromagnetic Engineering Calculators are general purpose analysis tools.  For instance, the Wavelength Calculator can be used to determine the length of a Monopole Antenna, while the Skin Depth Calculator is commonly used to determine the metal thickness for Microstrip, Stripline, and CPW transmission lines.  The Skin Depth Calculator is also used to determine the metal thickness for electroplating cavity assemblies and waveguide assemblies.  The final calculator is the Dielectric Heating Calculator, which is used to estimate the frequency-dependent power and electric field to heat a defined volume and mass of dielectric material in a defined time period.  If you do not see the calculator that you need for your problem, then Contact Us to determine if we can provide you with this calculator.
