TEM Wavelength Calculator Formula
λ = 300 / (F × √εr)
Formula Explanation
This TEM Wavelength conversion calculator determines the wavelength (λ) of a signal in a medium with relative permittivity εr. The frequency F is in GHz, and the formula accounts for the reduction of wave speed in dielectric materials by dividing 300 (speed of light in million meters per second) by the product of frequency and the square root of εr.
Uses of TEM Wavelength Calculator
The TEM Wavelength conversion calculator is useful for engineers and designers in:
- RF circuit and antenna design, determining proper trace lengths.
- Telecommunication system planning to calculate signal propagation.
- Educational purposes for understanding wave behavior in different media.
- High-frequency PCB design requiring precise wavelength calculations.
Formula Example
For a signal frequency F = 2 GHz and relative permittivity εr = 4:
λ = 300 / (2 × √4) = 300 / (2 × 2) = 75 λ
The wavelength in this medium is 75 units, helping designers adjust lengths for RF circuits or antennas.
