Propagation characteristics while entering tunnels are analyzed by using a ray-launching technique and the uniform theory of diffraction (UTD). RMS angular spread is studied and related to the "excitation zone." This paper presents interesting differences in the behavior of this parameter and the ...
They arise from unwanted diffraction and other effects, and are more fully described in Section 2.5.2.2. They typically contribute to very little wasted power on transmit but sometimes cause large or close-in targets outside of the main beam to produce spurious received echoes. These effects are...
[This is like what happens for diffraction, where the integral (16.25) appears, rather than a sum.] The corresponding angle Δθ0 satisfies, not (16.30) for m = 0, but rather (16.31)d sin Δθ0=λN. For small Δθ0, where sin Δθ0≈Δθ0, we may rewrite ...
Characterization of CMOS images sensors generally requires both optical and electrical simulations to account for the absorption, scattering, and diffraction from sub-wavelength features as well as the electrical transport of generated charge. In this example, optical simulations provide information about fi...

The peaks for elliptical polarization are slightly smaller than linear polarization since the field is spread over the radial directions. Thus, the peak photoionization in the elliptical polarization case is slightly smaller for ATI since the tunnelling mechanism strongly depends on the transverse momenta...
