Phase diagram for passive electromagnetic scatterers

Phase diagram for passive electromagnetic scatterers.

With the conservation of power, a phase diagram defined by amplitude square and phase of scattering coefficients for each spherical harmonic channel is introduced as a universal map for any passive electromagnetic scatterers. Physically allowable solutions for scattering coefficients in this diagram clearly show power competitions among scattering and absorption. It also illustrates a variety o...

Phase diagram to design passive scatterers

A phase diagram, defined by the amplitude square and phase of scattering coefficients for absorption cross-section in each individual channel, is introduced as a universal map on the electromagnetic properties for passive scatterers. General physical bounds are naturally revealed based on the intrinsic power conservation in a passive scattering system, entailing power competitions among scatter...

Projection Volumetric Display using Passive Optical Scatterers

In this paper, we present a new class of volumetric displays that can be used to display 3D objects. The basic approach is to trade off the spatial resolution of a digital projector (or any light engine) to gain resolution in the third dimension. Rather than projecting an image onto a 2D screen, a depth-coded image is projected onto a 3D cloud of passive optical scatterers. The 3D point cloud i...
