I teach Microwave Engineering course to Under Graduate Avionics Engineering students. This semester as the mode of teaching was online and students did not have access to ADS, so I searched for an free alternative and I have found Qucsstudio to be an excellent replacement. Please except my heartiest appreciation. By the end of semester I can contribute some examples of how to use Quccsstudio for teaching Microwave engineering. What is the methodology for contributing examples, please?
