The formation of an image by an ellipsoidal reflector under illumination from one of its foci is discussed.

We study theoretically and numerically intermodal four-wave mixing (FWM) in few-mode fibers in the presence of birefringence fluctuations and random linear mode coupling.

The literature currently maintains the assumption that mutual coupling is the mechanism that leads to the degradation of isolation between the active ports of antenna arrays.

The combination of Density Functional Theory and Pseudopotential Theory has been successfully applied to the description of point-defects in semiconductors.

First, the optical transition energies for the strained layer superlattice Si sub 4 Ge sub 4 /Si(001) are calculated using the quasiparticle self energy approach and compared to available data.

In a series of fundamental experiments, H. C. Montgomery1 has established that minority carriers play an important part in the currentnoise associated with semiconductors.

A theory to describe microphase separation of block copolymers dissolved in a good, nonselective solvent is presented.

Interest has recent]}' intensified in receiver structures which hopefully will permit higher data symbol rates than are possible with con1821 1822 T H E B E L L S Y S T E M TECHNICAL JOURNAL, D E C

Charge-transfer devices (CTD's), such as the bucket-brigade 1 (BB) and charge-coupled-device2 (CCD) shift registers, are currently of great interest.
