General method for focusing of waves using phase and amplitude compensation
Lars Egil Helseth
A general method for focusing of waves, based on phase and amplitude compensation, is applied to monochromatic, polychromatic and diffusive waves. Monochromatic waves may form spat…

Tight focusing of polychromatic waves using angular spectrum compensation in spatially dispersive media
Lars Egil Helseth
A general method for tight focusing of waves, based on compensation of the angular spectrum, is established. We apply the method to monochromatic, polychromatic and diffusive waves…

Roles of polarization, phase and amplitude in solid immersion lens systems
L. E. Helseth
By altering the polarization, phase and amplitude at the exit pupil, the intensity distribution near the focal plane of a Solid Immersion Lens(SIL) system can be changed. We have s…
