I hold a PhD in theoretical physics. As a PhD student and a post-doctoral fellow, I studied specifically atomic movement and growth in metals or on metal surfaces. Since I joined Ericsson Group in 1996, I have been working as a research engineer and pursuing MMICs design, RF module development and radio system build-up, from microwave to millimeter-wave in various technologies.

What is your title and/or role in the project?

I am a senior specialist in R&D at Ericsson Research. My role in Car2Tera is to drive the development of the Telecom demonstrator, i.e., short-range, high data-rate wired links using polymer microwave fibers (PMFs).

What are your contributions to the project? (Specify what deliverables and/or tasks you are responsible for)

Specifically,  I will contribute to the transition from the MMIC to the fiber, including concept development and HFSS design. Deliverables I am responsible for are: 1) specification of the Telecom demonstrator, 2) assembly of the demonstrator, and 3) verification of the demonstrator.

What challenges can you foresee in the project?

For the secondary demonstrator, the Telecom link, the required wide bandwidth (>40 GHz) will be challenging for MMIC designers. Developing a low-loss MMIC-PMF transition is not an easy task. Dispersion impact in the PMF will be a major limitation to the data-rate or link distance, and resolving the dispersion impact is not trivial at all.

How do you think the project outcome could affect our daily life?

The Telecom demonstrator is target at application in base stations for 5G networks and beyond. The impact of the project outcome on human and society can hardly over-estimated, as 5G and beyond wireless technologies will significantly change the life of more than 9 billion mobile subscribers who are going to enjoy the innovative new services the technology brings to us.

I’m professor in Microwave and Terahertz Microsystems at KTH Royal Institute of Technology, in Stockholm, Sweden.

What is your title and/or role in the project?

I’m Scientific Leader of the project, and responsible for all micromachining parts of the project, including the innovative micromachined beam steering antenna system of the novel sub-terahertz car radar sensor.

What are your contributions to the project? (Specify what deliverables and/or tasks you are responsible for)

My research team at KTH is responsible for D3.2, 3.4, 3.6, 4.1, 4.4, 4.6,

What challenges can you foresee in the project?

The project is very ambitious, and many people with different background have to find a common language to solve the major challenges together.

How do you think the project outcome could affect our daily life?

All of us are sitting in cars too much time of our lives. This new type of car radar sensor is targeting car accidents, and also autonomous driving, to which all of us are looking forward.

What is your title and/or role in the project?
I am the leader of WP3 (“Emerging technologies for future THz car sensors and networks “) which aims to use recent achievements in emerging 2D-materials and micromachining THz technologies, to develop groundbreaking technologies for the identified THz applications. This is the first attempt of using graphene-based electronics for communication and sensing applications above 100GHz; and graphene circuits would offer real advantages for the targeted applications. This is a direct exploitation of latest results of the Graphene Flagship Programme towards an industrial-level demonstrator. Graphene MMICs according to the results achieved at Chalmers Univ., so far only attempted below 100 GHz, have shown extraordinary linearity, as compared to semiconductor circuits. This project requires very large bandwidths (100 GHz) and therefore would highly benefit from the linearity of graphene field-effect transistors. My role is to coordinate the works within WP3, and after its completion I am responsible for the cooperation of the activities performed within WP1,8,9 which involve the development of technological specifications to guarantee a well-structured technical implementation of the project, application of graphene, and later for the results dissemination. I am also taking part in the operational management of the project

What are your contributions to the project? (Specify what deliverables and/or tasks you are responsible for)
In this project we will demonstrate the potential of graphene to be used in handling very demanding signals at frequencies not yet investigated, namely D-band 110-170 GHz and G-band 140-220 GHz. My main task in the project is to fabricate and characterise high quality graphene on SiC and other substrates including sapphire, SiO2 and other 2D materials as hBN, with high transport parameters, repeatability and uniformity, as required by sub-THz devices, developed in WP3. Various protocols of graphene growth and transfer onto arbitrary substrates will be verified towards high device performance and the industrial implementation. This will provide significant advance over existing sub-THz technologies operating at millimetre wave (mm-wave) frequencies. The devices are to be applied in the project´s system demonstrators realized within WP5 and WP6.

What challenges can you foresee in the project?
The key challenge is to develop high quality graphene with such parameters and technological solutions that would satisfy the requirements of sub-THz devices i.e. MMIC-grade uniformity, OFF/ON ratio of channel resistance >> 5, accurate nonlinear device models, MMIC-processing, interfacing with Si THz-platform and that would later result in the creation of the economically and commercially viable product. If the emerging technologies can be successfully implemented in laboratory, the demonstrators will utilize them to achieve outstanding performance targeting real-world applications.

How do you think the project outcome could affect our daily life?
With alarming figures of annual road fatalities worldwide, safety has become a key issue for the whole automotive industry. Car radar sensors are now a vital part of any modern automobile design, enabling greater degree of vehicle automation. They provide to the driver accurate and reliable information on the car surroundings in the most effective and least distractive manners, allowing the control unit to take preventative or corrective actions. They are fundamental in helping car manufacturers to produce models that are safer, more fuel efficient and more comfortable to drive. Application of graphene can significantly contribute to increasing sensors capabilities and thus the development of safer and more reliable systems. Apart from application in sensors, graphene is an attractive material to be used in order to increase data transfer not only in cars but in many areas of our daily life.
