The work on developing electromagnetic absorption and shielding material began in 2012. Since then SMW team of scientists, along with two leading Estonian universities and one specialised Institute, have invested a significantamount of time studying existing weaponry and analyzing prospective optimized solutions based on SMW EMBloq technology.

Numerous scientific papers have been published, ex.:

  • Vibration-Assisted Sputter Coating of Cenospheres:A New Approach for Realizing Cu-Based Metal Matrix Syntactic Foams (A. Shishkin, M. Drozdova, V. Kozlov, I. Hussainova, D. Lehmhus)
  • Microwave Reflectance and Transmittance Properties of Conductive Composite Materials (A. Shishkin, T. Koppel, V. Mironov, I. Hussainova, J. Lots, H. Haldre)
  • Electromagnetic Shielding Properties of Ceramic Spheres Coated With Paramagnetic Metal (T. Koppel, A. Shishkin, I.Hussainova, H.Haldre, P. Tint)
  • Reflection and Transmission Properties of Common Construction Materials at 2.4 GHz Frequency (T. Koppel, A. Shishkin, H. Haldre, N. Toropov, P. Tint)
  • Snow Microwave Reflection at Mobile Phone Frequency Bands (T.Koppel, I.Vilcane, P. Tint, A. Shishkin)

A product has now been developed that accomplishes both missions:

–  addresses emerging physical risk factors of EM radiation,

–  delivers cutting-edge structural material for aerospace, sea and land vehicles.

In July 2019 SMW received a grant from the Ministry of Defence of the Republic of Latvia to develop a lightweight shielding material to protect various types of vehicles from electromagnetic weapons, such as EMP and DEW. 

R&D work is ongoing.

EMBloq provides a major advantage and added value, as compared to similar products that are in existence, because of the negligible near-zero carbon footprint it provides – delivering environmentally net-positive effect

EMBloq is fully in line with the European smart specialization strategy, and it delivers additional regional benefits:

  • One of EMBloq panels’ elements contains fly-ash cenospheres, utilization of which improves the ecological footprint. Fly ash is a waste product generated from burning natural mineral resources (coal). Largest known sources of this material are located in Poland, UK, Netherlands, whereas one of the potential sources is resulting from the burning of oil shale in Latvian and Estonian thermoelectric power plants. Specifically, there are vast resources of this waste material in Ida-Virumaa region of Estonia.
  • The use of magnesium is more environmentally friendly (resulting in lower CO2 emissions) than in the current case of widely-used aluminum.
  • Magnesium has superior characteristics, as compared to other structural materials. Magnesium is ~ 33% lighter than aluminum by density and thus possesses higher specific strength and also significantly higher damping factor (capacity for absorbance).
  • Production of EMBloq panels in some cases involves 3D printing (additive manufacturing process) allowing for higher efficiency by way of a significant reduction in raw materials used, while minimizing waste and losses of feedstock material.

EMbloq production is environmentally friendly. Additionally, vehicles that employ EMBloq panels will be lighter-weight than in the cases of using other protective materials of analogues function. This results in reduction of fuel consumption and respectively of CO2 emissions.
