\section{Properties of the Fourier Transform}
\label{app:fourier}
Let us name $f(x)$ a function, and $F(X)$ its Fourier transform. We
use here the simple, non-unitary convention
\begin{itemize}
\item Definition: $F(X) = \int_{-\infty}^{+\infty} f(x) e^{-2i\pi x X} dx$
\item Linearity:  $h(x) = a f(x) + b g(x)$, then $H(X) = a F(X) + b G(X)$
\item Translation:  $h(x) = f(x-x_0)$, then $H(X) = e^{-2i\pi x_0 X} F(X)$
\item Shifting: $h(x) = e^{2i\pi x X_0} f(x)$, then $H(X) = F(X-X_0)$
\item Scaling: $h(x) = f(ax)$, then $H(X) = \frac{1}{|a|}F(\frac{X}{a})$
(the so-called \textit{time reversal} property is obtained with $a=1$
\item Conjugation: if $h(x) = \bar{f}(x)$, then $H(X) = \bar{F}(-X)$
\item Integration: With $X=0$ in the definition\\
$F(0) = \int_{-\infty}^{+\infty} f(x) dx$
\item Convolution: $h(x)= f(x) * g(x)$ then $H(X) = F(X) G((X)$. \\
The Fourier Transform of a product of two functions is the convolution of
the Fourier Transforms of the functions.
\item Uncertainty principle:  the more concentrated $f(x)$ is, the 
more spread out its Fourier transform $F(X)$ must be. In particular, 
the scaling property of the Fourier transform may be seen as saying: if 
we squeeze a function in $x$, its Fourier transform stretches out in $X$. 
It is not possible to arbitrarily concentrate both a function and its 
Fourier transform. 
\end{itemize}
The definition, illustrated here with scalars, also holds for $x,X$ 
being 2-D vectors in Euclidean space, the product in the definition 
being a standard dot product of these vectors.
