A microphotonic mm-wave modulator using simultaneous RF and optical resonance in an electro-optic medium is presented. Theory and simulation of modulator operation is discussed, and experimental results demonstrating modulation using simultaneous resonance in the mm-wave range are reported.

In this paper MV-algebras, the algebras of èukasiewicz in®nite-valued logics, are interpreted in a structure of bets, and a subjective interpretation of ®nitely additive measures on MV-algebras is given. Ó 2000 Elsevier Science Inc. All rights reserved.

Depolarized light scattering spectra of orthoterphenyl showing the emergence of the structural relaxation below the oscillatory microscopic excitations are described by solutions of a schematic mode-coupling-theory model. Ó 1998 Elsevier Science B.V. All rights reserved. PACS: 64.70.Pf; 61.20.Lc

We use the local linear momentum density in Laguerre±Gaussian beams to investigate classically the trajectory of the Poynting vector for light of any polarisation. Some of the diculties of interpretation of the local angular momentum density are discussed. Ó 2000 Published by Elsevier Science B.V.

The Lyapunov function method is the focus of this paper in proving marginal stability, asymptotical or globally asymptotical stability of discrete dynamic systems. We show that the slightly relaxed versions of the well known sucient conditions are also necessary. Ó 2000 Elsevier Science Inc. All rights reserved. AMS: 90A16
