SUMMARY
The upper cutoff frequency for a rectangular waveguide is a critical concept in microwave engineering, determined by the waveguide's dimensions. This frequency marks the transition point where the longitudinal component of the electromagnetic wave changes from imaginary to real, resulting in wave attenuation. The cutoff frequency is not solely dependent on the material of the waveguide but is fundamentally tied to its geometric properties. Understanding this phenomenon is essential for effective waveguide design and application.
