The analytical solution for the propagation of the laser beam with optical vortex through the system of lenses is presented. The optical vortex is introduced into the laser beam (described as Gaussian beam) by spiral phase plate. The solution is general
This expression may prove especially useful for architects, engineers (civil or solar energy), and solar energy systems investors who wish to assess the solar energy availability in Greece throughout the year by using mode-III solar receiving systems. Seasonal solar energy sums were also estimated....
There have been a number of applications in civil and military aircrafts, launch vehicles, wind turbine blades, and marine structures in which composite and sandwich material systems were used as primary structures [20]. Sandwich structures can often sustain large deformations under constant load, ...
