Internship Description:

Coated glass for automotive IR cut is a promising solution for future sustainable car air conditioning. Metallic coating is applied on glass to filter out the heating energy of the solar bursts, protecting the car of overheating in the sunlight. This sustainable solution is creating a problem for modern telecommunication by creating a Faraday Cage for mobile communication radio waves preventing passengers from access to the mobile network. Frequency Selective Surfaces are a potential solution for this issue by selectively creating a pass band filter for the needed frequencies.



                                a) Carline shape                 b) 3D model of the car                c) Current distribution on the car


One major goal through such a research is investigating the optimal FSS structure for improving the field distributions inside a fully coated glass vehicle. This way, we could have a better understanding of the propagation phenomenon and the potential obstacles of utilizing mobile modules inside a car. Various FSS shapes and glass positions will be studied to assess the main parameters affecting the field distribution. Different wave sources polarizations from different incident angles will be considered in order to cover all the automotive road source scenarios. Furthermore, the result of such an investigation could be a parametric model which can be used in any automotive design.
