Abstract :
Nondiffracting X waves can be described in a unified way within the angular-spectrum representation; we first discuss this general mathematical formalism. We also present a closed-form expression for axisymmetric high-frequency X waves. Finally, the nondiffracting pulses obtained via the space-frequency synthesis of conical waves are illustrated
