Propagation Speed of Electromagnetic Waves

Propagation Speed of Electromagnetic Waves

Electromagnetic waves are consistent with Ampere's law. Assuming there is no conduction current Ampere's law is given as:

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences

A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

Background:

Microresonator-based frequency combs are crucial for precise optical measurements.
Understanding nonlinear conversion efficiency is key to optimizing comb generation.

Purpose of the Study:

To investigate the factors influencing nonlinear conversion efficiency in mode-locked frequency combs.
To determine how dispersion conditions affect comb efficiency.

Main Methods:

Analytical modeling of nonlinear dynamics.
Numerical simulations of pulse propagation in microresonators.
Analysis of efficiency dependence on spectral width and comb line count.

Main Results:

Efficiency degrades with increasing comb spectral width and number of lines.
Efficiency is solely dependent on microresonator cold-cavity properties.
Efficiency improves with increased coupling coefficient and in multi-soliton states.

Conclusions:

Nonlinear conversion efficiency in microresonator frequency combs is fundamentally limited by spectral broadening.
Optimizing coupling and operating in multi-soliton regimes are viable strategies for enhancing comb efficiency.
