Transformation Electromagnetics Based Analysis of Waveguides With Random Rough or Periodic Grooved Surfaces

A computational model is introduced which employs transformation-based media to increase the computational performance of finite methods (such as finite element or finite difference methods) for analyzing waveguides with grooves or rough surfaces. Random behavior of the roughness is taken into accou...
