AFAIK, yes, but not often. You have to get exciting results and good recommendations(or trusted coauthors). Showing experiments frees peers from extra deep checking, and reduces questions. Many good papers were scrapped because there were no interested specialists to check calculus and models. Maybe there is more freedom to circuit analysis, but in fundamental wave propagation and antenna theory, you have to think about some basic demonstration.
Good question, Pengda! I published one such paper recently* and I had to be careful about justifying comparing results from my formulae, only to computer simulations...
