Terahertz Engineering
Material dispersion refers to the phenomenon where the phase velocity of a wave varies with frequency as it propagates through a medium. This causes different frequency components of a signal to travel at different speeds, leading to pulse broadening and potential distortion in time-domain signals. Understanding material dispersion is crucial in modeling and simulating terahertz devices, as it affects the performance of these systems by influencing how signals behave in various materials.
