1. The Airy function includes a "tail" which extends into the classically forbidden band gap.
2. The invention concerns a method for making an extreme ultraviolet microlithography transmission modulator, characterised in that it consists in obtaining adamantine amorphous carbon by a process using a plasma consisting of a mixture of acetylene and argon and maintained by the power of a microwave source; in depositing a thin adamantine amorphous carbon film on a substrate with low absorption in extreme ultraviolet whereto is applied a variable polarisation; in varying the forbidden band between 1 and 2 eV through control of the argon partial pressure and in varying the corresponding extinction coefficient so as to modulate the modulator transmission without modifying the thickness of the deposited film.
