The invention relates to an apparatus comprising a differential driver module configured to generate at least one differential signal having steep rise and fall times for at least partially reducing common-mode noise. The invention also relates to a method for causing the differential driver to generate the signal and a system comprising the differential driver and a conductor module for transmission of the generated differential signal. A computer program for performing the method and a computer-readable medium is also part of the invention.

Generation of differential signals

The disclosure pertains to a method of orientating particles by their easy axes in a selected area of a composite comprising the particles dispersed in a matrix. The method comprises liquefying and then solidifying the matrix at the selected area while applying an external magnetic field on the composite. The composite can be used for a transmission line component for directing high frequency electromagnetic waves. The particles are preferably superparamagnetic nanocrystallite particles and matrix is preferably a polymeric material.

Electromagnetic wave transmission lines using magnetic nanoparticle composites

In one or more embodiments described herein, there is provided an apparatus comprising a substrate, and a plurality of carbon nanotubes (semiconducting nano-elements) disposed and fixed with said substrate. The nanotubes are disposed and fixed on said substrate such that they define a carbon nanotube network substantially at the percolation threshold of the network. As the network is at the percolation threshold, this provides for one or more signal paths extending from an input region to an output region. The apparatus is configured to, upon receiving particular input signalling via the input region, provide particular predefined output signalling at the output via the one or more signal paths, the particular output signalling being predefined according to the one or more one signal paths.

Apparatus and associated methods in relation to carbon nanotube networks

In one embodiment, an apparatus comprises a nano-scale spectrum sensor configured to be electromagnetically excitable at a predetermined frequency based on received ambient electromagnetic radiation. The apparatus is also configured to be able to use this excitation of the nano-scale spectrum sensor to thereby determine ambient electromagnetic radiation spectrum usage.

Apparatus for spectrum sensing and associated methods

The invention relates to a method for enhancing an antenna performance, wherein the property of the antenna substrate is modified by using an ultrasonic field. The invention also relates to an antenna comprising the modified antenna substrate, and to an apparatus comprising the modified antenna substrate.
