A New Dielectric Material [PDF]
Nature, 1952 I HAVE prepared a ceramic material which, although apparently being pure rutile, has quite different dielectric properties. It was obtained by heating pure titanium oxide (TiO2) to a temperature of 1,400° C., as described elsewhere1. X-ray analysis leads to the same Debye–Scherrer pattern as rutile (axis ratio 1 : 0.911).

Observation of backscattering-immune chiral electromagnetic modes without time reversal breaking
, 2011 A strategy is proposed to realize robust transport in time reversal invariant photonic system. Using numerical simulation and microwave experiment, we demonstrate that a chiral guided mode in the channel of a three-dimensional dielectric woodpile ...

Dielectric materials in magnetic resonance
Concepts in Magnetic Resonance Part A, 2011 AbstractHigh permittivity materials find extensive use in high frequency communications devices due to their small size (compared to lumped element circuits), low losses and physical robustness. Recently, these types of materials have been applied in high field magnetic resonance imaging, based upon earlier work in electron paramagnetic resonance. This
