The IOP’s Dielectrics and Electrostatics Group is hosting its biennial Dielectrics conference from 14th-16th April 2021 at the Institute of Physics, London, UK, to explore the ever-expanding area of dielectrics. The Dielectrics 2021 conference will run under the theme “From Fundamentals to Applications” to encourage a wide range of topics to be covered and scientists to participate. The conference is organised in four core topics, including Theory and Modelling of Dielectric Materials, Advanced Characterisation of Dielectric Materials, Dielectrics for Biological Applications, and Dielectrics for Electronic Devices. Contributions from both academia and industry are welcome covering areas in physicis, chemistry, materials science, engineering and technology.
