# How to show tilde in superscript

I would like to show a tilde in the superscript of a letter. For example

F^{\tilde{}}


But it does not look good. Any suggestions?

Thanks and regards!

I assume you want something that looks like F~, and that you're just using the tilde as a "squiggle" to name something. If you're in math mode, F^{\sim} looks more like what you want.
