Fabrication of Folded Wave Guide Structure by Laser Micromachining

Mounashree B S | Mr Sudhir B S

Abstract: In this thesis, a folded-waveguide slow-wave circuit working on 220GHz central frequency is targeted for investigation. The thesis includes two major parts, i. e. the theoretical study and electromagnetic field simulations; Our cold-circuit analysis reveals that the pass-band of the 220GHz central frequency folded waveguide is ~80GHz, which is between the cut-off frequency and the first stop-band. Parametric cold-circuit study provides better knowledge about how the varying structural parameters can influence the cold- circuit parameters. Optimization of cold-circuit properties via simulation also indicates ~20GHz bandwidth of the circuit, and this is used as the basis of further beam interaction circuit simulations
