Cardinal Sine Surface

Cardinal Sine Surface

The cardinal sine surface is a three-dimensional projection of a cardinal sine function in two dimensions. Drawn on this print is the unnormalized function, which was introduced by Philip M. Woodward in 1952 Woodward and Davies (1952).

\[% f(n) = \begin{cases} \frac{\sin{\sqrt{x^2 + y^2}}}{\sqrt{x^2 + y^2}} & \quad \text{for } x = y \neq 0\\ 1 & \quad \text{for } x = y = 0\\ \end{cases} \]
