How to Calculate Cutoff Wavelength?
Cutoff Wavelength calculator uses Cutoff Wavelength = (2*Refractive Index*Plate Distance)/Mode Number to calculate the Cutoff Wavelength, Cutoff Wavelength refers to the longest wavelength that can propagate effectively in a waveguide or transmission line, determined by the physical dimensions and operating frequency of the structure. Cutoff Wavelength is denoted by λcm symbol.
How to calculate Cutoff Wavelength using this online calculator? To use this online calculator for Cutoff Wavelength, enter Refractive Index (nr), Plate Distance (pd) & Mode Number (m) and hit the calculate button. Here is how the Cutoff Wavelength calculation can be explained with given input values -> 2124 = (2*2*0.2123)/4.
