Far-field emission narrowing effect of microdisk lasers
TL;DR: A scalar diffraction theory in the cylindrical coordinate is developed to explain such an emission-angle-narrowing phenomenon and numerical calculation based on a vectorial theory is carried out to explain the measured polarization state as discussed by the authors.

A Direct Imaging Method for Electromagnetic Scattering Data without Phase Information
Zhiming Chen,Guanghui Huang +1 more
TL;DR: It is proved that the imaging resolution of the method is essentially the same as the imaging results using the scattering data with the full phase information, which implies the imaginary part of the cross-correlation imaging functional always peaks on the boundary of the obstacle.

Effective models in evaluating radio coverage on single floors of multifloor buildings
Jenn-Hwan Tarng,T.R. Liu +1 more
TL;DR: In this paper, an effective site-specific hybrid model was developed to predict the path loss and the effective radio coverage on single floors, combined with a two-dimensional (2D) model and an easy-to-use direct-transmitted ray (DTR) model, is incorporated with the building blueprint in usage.
