To derive and validate a simple analytical model for the detected signal in terahertz time-domain spectroscopy using photoconductive antennas and optimize system performance.
Derived an analytical signal equation by coupling classical charge transport equations with dipole radiation equations.
Validated the formulation by comparing calculated results against published theoretical data and newly acquired experimental measurements.
Performed a detailed noise analysis to evaluate and optimize key experimental variables.
The detected terahertz signal depends primarily on the semiconductor material carrier lifetime and the laser pulse duration.
The analytical formulation decouples distinct experimental parameters, allowing targeted adjustment of operating conditions to minimize noise and maximize dynamic measurement range.
