Low-loss compact waveguiding with te modes in metal/dielectric waveguides for planar lightwave circuit / Mohd Zulkifli Chik

A waveguide is a structure which guides waves, such as electromagnetic waves or sound waves. There are different types of waveguide for each type of wave. The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves. Wavegui...
