[math]f[/math] is even iff [math]f\in\operatorname{Ker}(T -I)[/math]. If [math]f\in\operatorname{Ker}(T -I)\cap C^\text{abs}[/math] then [math]\mathcal{F}f = \mathcal{F}{-1}f[/math], so [math]\mathcal{F}^2f = \mathcal{F}\mathcal{F}^{-1}f = f[/math]. How it is not specified if [math]f[/math] is even or not from your question.

Math requires a natural aptitude of "the willingness to practice lots".

So... I can't really find a lot of information on this. How do you protect sensitive electrical circuitry from an EMP?

What kind of shielding is used?

For example, I read that Air Force One has special shielding for EMPs... but what is that exactly?

Google searches result in lots of paranoid tin-foil and snake-oil tier sites. Any discussion or resources (books, links, etc) would be awesome.
