Modeling the longitudinal intensity pattern of diffraction resistant beams in stratified media

Area of Science:

• Optics and Photonics
• Wave Propagation

Background:

• Frozen wave (FW)-type beams offer diffraction-resistant properties.
• Stratified media pose challenges for beam propagation due to multiple interfaces.

Purpose of the Study:

• To develop a theoretical method for controlling spatially shaped diffraction-resistant beams in stratified media.
• To enable precise control over the longitudinal intensity pattern of FW beams.

Main Methods:

• Development of a theoretical framework for FW beam propagation.
• Implementation of a matrix method for analyzing multi-layered stratified media.
• Investigation of thin-film applications for minimizing interface reflections.

Main Results:

• Demonstrated ability to shape and control the longitudinal intensity of FW beams.
• Successful propagation and control through non-absorbing stratified media with numerous layers.
• Validation of the theoretical method for diffraction-resistant beam manipulation.

Conclusions:

• The proposed theoretical method effectively controls diffraction-resistant beam patterns in stratified media.
• The technique is robust against multiple reflections and transmissions.
• Potential applications span remote sensing, medical diagnostics, and military technologies.
