Parametric Amplification in a 1D Lossy Cavity with Time-Varying Permittivity: FDTD Analysis
This study examines the effects of time-modulated permittivity in a lossy cavity enclosed by perfect magnetic conductor (PMC) walls, where the modulation frequency is set to twice the input frequency to observe parametric amplification. A parametric study of three key parameters is conducted to identify the conditions under which parametric amplification occurs. The findings show that parametric amplification is achievable even in the presence of material loss.
