Therefore, the problem is solved by determining the value … WebAbout this calculator. This calculator computes the power reflectivity and transmission of a plan wave at a dielectric interface using the Fresnel equations. These depend on the refractive indexes of the two materials as well as the incidence angle and polarization of the wave in material 1. Therefore, the results are different for S ... Web5. sep 2024 · Example Calculation. For a VSWR of 2, the mismatch loss is calculated to be 0.51. 89% of the power is transmitted forward, while 11% is reflected back into the source. As the VSWR increases, the quality of the match deteriorates and more power is reflected back. For a VSWR of around 5.9, half the power is reflected back. dsm2 brick receiver
