  • Vimal's poster, 'New carbon nanotubes (CNT) interconnects', discussed the use of this novel material solution which outperforms traditional interconnect materials, such as copper, with respect to their electrical and thermal conductivity properties.


The dielectric properties of materials govern the way in which they interact with electromagnetic signals and waves. NPL possesses a wide range of facilities for measuring these properties at RF and Microwave frequencies. Measurements can be performed on both solids and liquids and on low, medium and high loss materials.

Electronics Interconnection

Electrical interconnects are an intrinsic part of any electronic system. The interconnect has to perform on a wide range of substrates and under wide range of environmental conditions, and survive induced stresses from thermal, mechanical, corrosive and electrical factors. In many instances the capability of the interconnect is a road block to realising the full performance of the functional circuit.

The demand for traceable electrical and magnetic measurements is broadening as new materials and techniques have brought the need for these measurements to new areas of industry. There are a large number of parameters of interest, covering an ever-increasing range of values and frequencies. To provide traceability for these, NPL is involved in continuous development of measurement techniques and facilities. This gives NPL a unique range of facilities and experience in magnetic measurements.
