EXPERIMENTAL VALIDATION OF AN ELECTROMAGNETIC JET AT THE OUTPUT OF A RECTANGULAR WAVEGUIDE

This study explores the generation of electromagnetic jets using a PTFE-loaded rectangular waveguide with an optimally designed tip. Due to the complexity of the structure, an optimization study was conducted to enhance computational efficiency while ensuring accuracy. Two prototypes were fabricated and experimentally tested, with key measurement challenges successfully addressed. The results demonstrate that a PTFE-loaded waveguide can effectively generate an electromagnetic jet, paving the way for potential applications in high-resolution imaging, beam shaping, and advanced electromagnetic wave control.
