The behaviours of the electric and magnetic fields inside a conducting cylinder with a single axial aperture are not as well understood as is commonly believed. The experimental measurements and computer simulations described in this paper comprise a

Reflectance data (0.001–4.0 eV) from several large (a typical surface area 3×3 mm2) single crystals of Ba1−x KxBiO3 (x=0.04, 0.37) (BKBO) and Ba1−x,RbxBiO3 (x=0.37) (BRBO) were obtained by Fourier transform infrared (FTIR) and ellipsometric me

The sensitivity of an electro-optic (EO) field sensor depends inversely on the dielectric constant of the nonlinear crystal. In EO sensors based on lithium niobate the effective value of this dielectric constant is affected by dielectric relaxation e

Strontium barium niobate has the tungsten-bronze structure with a tetragonal unit cell, and it exhibits negative thermal expansion along the c axis between −120°C and room temperature while having a positive thermal expansion along the a axis for

Experimental studies of the spatial and temporal fluctuations in photorefractive electro-optic (EO) field sensors have revealed that their maximum intrinsic responsivity is limited by incoherence in the polarization of the probe beam. This incoherenc

Responsivity measurements are reported for LiNbO3 electro-optic field sensors operated under applied electric fields at ac frequencies in the vicinity of the acoustic resonance values of the crystals. At these frequencies, piezoelectric effects domin

We have measured the electro-optic response of LiNbO3 and SrxBa1−xNb2O6 crystals to be used for electric-field sensors. Our results indicate that optically induced refractive index variations (photorefractivity) in the crystals affect the temporal

Raman and infrared measurements were conducted on Ba 1−x K x BiO 3 single crystals as a function of potassium concentration x. The sample with x=0.5 was found to superconduct below 32 K, while the other two samples with x=0.2 and 1.0 were semicondu

The electrical field distribution over the focal region of a Gaussian beam, incident at 45° and focused onto a perfectly conducting infinite plane, is calculated numerically by summing the plane waves in an angular spectrum representation. The beam
