Model ID: 4473
The optimization of components with respect to geometrical design parameters is a common task in microwave engineering. In this model the reflection coefficient of a waveguide structure is minimized, and the sensitivities of the real and imaginary parts of the reflection coefficient are extracted using the parameterized geometry and adjoint sensitivity features of COMSOL Multiphysics. The example geometry is a waveguide 90-degree corner bend with the outer corner replaced by a metallic wall section at 45 degrees angle to the connecting straight waveguide sections.
