So basically, as an undergrad it’s quite expensive to attend conferences. My paper got accepted to a more specialized IEEE conference. I had previously built simulation tools from scratch for computational EM (a more graduate-oriented topic), however I hadn’t quite discovered anything new. I am also quite confused if having a conference paper to vouch for these tools will provide any additional benefit when applying for PhD as opposed to just showing that they indeed do work. If yes, then is it worth spending the money to present my work?
