How to show tilde in superscript

Question

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!

Answer 1

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.

Answer 2

The "~" rendering depends on the font, some have centre base, some are positioned much higher (more like "^" and less like "-") Play around with different fonts to get a wanted non-ugly "~".
