A Gregorian antenna with the main reflector illuminated by a magnified image of a small horn aperture has been built and tested from 12 to 30 GHz.

The quantitative imaging of individual impurity atoms in annular dark-field scanning transmission electron microscopy (ADF-STEM) requires a clear theoretical understanding of ADF-STEM lattice imagi

We demonstrate submicron resolution imaging using picosecond acoustic phonon pulses.

By using an atomic-force-microscope-based technique, we image the vibration of high-frequency, bulk-mode, thin-film resonators.

This work reports the study of ion-implantation induced damage and annealing in the highly anisotropic semimetal graphite using high resolution transmission electron microscopy.

Spatially and spectrally resolved microscopic images of spontaneous and stimulated emissions are imaged at the mirror facets of a GaAs T-shaped quantum wire laser with high uniformity.

The concept of electron localization has long been accepted to be essential to the physics of the quantum Hall effect(1,2) in a two-dimensional electron gas.

The theory of Fresnel diffraction is the basis for an understanding of optical resonators1"5 and of optical modes of propagation.

We report scanning tunnelling microscopy images of polaronic charge ordered patch on the layered ferromagnet La(2-2x) Sr(1+2x) Mn(2)O(7), x=0.32.

Use of a phased array in a satellite of large aperture diameter is proposed in Ref. 1 to form a narrow beam to communicate with ground stations in the United States.
