Electrochromic windows allow for an improved management of solar heat gains in buildings and enhanced visual comfort of building users. All-solid-state electrochromic devices can be especially durable. During their fabrication lithium has to be inserted, p ...

Building materials attenuate the microwaves used for telecommunication depending on their composition and thickness. Modern windows contain glass with a metallic coating. This might cause a low quality of cell phone reception inside some buildings. In orde ...

In order to reduce the energy consumption of buildings, modern windows include metal-containing coatings. These coatings strongly attenuate the microwaves used for mobile communications. Here, we present a novel approach to improve radio signal transmissio ...

A simulation model and an experimental characterization of energy saving glazing transparent to mobile communication frequency up to 40 GHz is presented. A previous study showed that laser structured energy efficient windows with a frequency selective surf ...

With the purpose of reducing the heating energy in buildings, it is common practice to install energy-efficient windows to increase the thermal insulation of a façade. These insulating glass units (IGIJ) include a thin silver coating acting as an infrared ...

We demonstrate monocrystalline growth of GeSn on Ge and Si substrates by co-sputtering. We discuss the evolution of film growth with thickness, elucidating the effects of substrate temperature, sputtering source, and the importance of hydrogen dilution in ...

Incorporation of Mo into pure WO3 thin films is of interest for electrochromic devices, as it improves colour neutrality in the dark state. Existing literature still lacks reliable quantitative data on the complex dielectric function of such coatings. In t ...

Electrochromic (EC) glazing helps manage daylight and solar heat gains in building, thereby allowing a reduction in energy consumption caused by heating, cooling, and artificial lighting. This study relates the optical and electronic properties of nanoporo ...

Novel mobile communication technology such as 5G will provide a more efficient and reliable platform for the development of the Internet of Things. However, microwaves in the range of 5G frequencies are strongly attenuated by modern energy-efficient glazin ...

This study explores the suitability of a basket -based solar cooker for cooking in Uganda, an equatorial country. The solar cooker is designed to be easily constructed and based on recycled and locally available materials. Its performance in terms of cooki ...

Solar cooking is one possible solution to reduce the domination of fossil fuel in the domestic sector and to benefit from renewable energy. This study assesses the solar cooking potential in Switzerland. A nodal model, based on energy balance equations of ...

The present invention concerns an insulating glazing unit (1) adapted to let pass electromagnetic radiation with low transmission loss for receiving electromagnetic radiation. The insulating glazing unit (1) comprises: a first windowpane (3) defining at le ...

The present invention concerns a laser engraving device (1) for engraving a target surface (17). The laser engraving device (1) comprises: a beam splitter (7) for dividing a processing laser beam (25) into a plurality of engraving laser beams (27); a first ...

A real case study and characterisation of modern energy efficient windows allowing mobile communication is presented. An earlier study had shown that laser scribing of energy saving coatings allows highly reducing the microwave attenuation (from 30 to 1-3d ...

Multiple Input Multiple Output (MIMO) systems are increasingly used to support the rapid growth in mobile traffic. Their ability of multiplying the data capacity is especially suitable in 4G-5G wireless railway communications. However, MIMO efficiency is l ...
