\"\ud83c\udf6b\"<\/span>\"\ud83c\udf68\"<\/span>This study presents the first homemade THz Time Domain Spectroscopy (THz-TDS) system in Thailand, developed to overcome the high cost and limited availability of commercial systems. The setup includes locally made photoconductive antenna (PCAs) (using electron-beam-irradiated SI-GaAs) and a Ti:Sapphire femtosecond laser, achieving high signal-to-noise ratio and broad bandwidth. System parameters\u2014like laser power, bias voltage, and scan resolution\u2014were carefully optimized to enhance performance.<\/div>\n
\"\u2728\"<\/span> The system was validated through material characterization experiments, such as measuring the refractive index and thickness of a silicon wafer, and addressing challenges in liquid-phase measurements, including internal reflections and window material selection. A dry-air enclosure was used to reduce moisture interference.<\/div>\n
\"\u2728\"<\/span> This work fills critical gaps in the THz-TDS field by providing a cost-effective, high-performance solution and practical guidelines for researchers in resource-constrained environments.\"\ud83c\udf66\"<\/span>\"\ud83c\udf67\"<\/span><\/div>\n
