A low profile radiating element with nearly hemispheric coverage for satellite communications on-the-move hybrid array antenna [PDF]
, 2010 A novel design solution of a dual-linearly polarised Ku-band low-profile radiating element for low elevation angle coverage (down to 10° above horizon) is presented. Such an element is suitable for full-duplex Satellite Communications On-The-Move (SCOTM)

On the dragging of light by a rotating medium [PDF]
, 2007 When light is passing through a rotating medium the optical polarization is rotated. Recently, it has been reasoned that this rotation applies also to the transmitted image.

Polarisable dielectrics for m.o.s.t.s
Electronics Letters, 1970 The use of a new and polarisable dielectric layer has made it possible to obtain large threshold-voltage shifts in m.o.s. capacitors.

Polarisation and Energy Loss in Dielectrics [PDF]
Proceedings of the Physical Society of London, 1913 The Paper discusses the relations which should exist between the coefficients in Pellat's equation (as modified by Schweidler) giving the displacement in a viscous dielectric as a function of the time of charge and the P.D. It is proved that where the polarisation current of a dielectric under the action of a steady E.M.F.

Circularly polarised dielectric resonator antenna
Electronics Letters, 1994 A circularly polarised dielectric resonator antenna is reported. The circular polarisation is obtained by exciting the two orthogonal HE/sub 11 delta / modes of a cylindrical ring dielectric resonator in phase-quadrature. Measured results show that the antenna has an axial ratio of less than 3 dB over a beam width of 100 degrees with a minimum value of

90° dielectric polariser in circular waveguide
Electronics Letters, 2000 Experimental results for a 90° dielectric polariser in a circular waveguide are presented. A small slot notched into the circular waveguide wall, used for the accurate alignment of the dielectric plate, has led to a decrease in the relative phase shift by 15.7%. A new U-shape impedance matching structure results in a bandwidth of 12.4%.

Computer simulation of bistable switching in a nematic device containing pear-shaped particles [PDF]
, 2006 We study the microscopic basis of bistable switching of a confined liquid crystal via Monte Carlo simulations of hard pear-shaped particles. Using both dielectric and dipolar field couplings to this intrinsically flexoelectric fluid, it is shown that ...
