A question related to materials. Will the semiconductor and rare materials crisis lead to “creative” new production technologies ? Has it had a bad impact on research in the last couple of years?

  1. from Elwalid Mohamed Elamin to everyone: 8:37 PM

Thank you Prof. Bozzi for the information. I have one question, what are the challenges in the semiconductor and microelectronics point of view for the research in the 6G THz communications?

  1. from Tramontana to everyone: 8:46 PM

I have a question for professor Bozzi on wearable devices. Nowadays we have for example watches that can measure the pulse rate and other parameters. Are modern devices accurate enough to be used to monitor people which for example have heart diseases?

  1. from Abdulrahman Widaa to everyone: 8:49 PM

A question to Prof. Bozzi: would you commet on the prospects and challanges of SAW/BAW sensors?

  1. from Mohamed Mabrouk to everyone: 9:02 PM

A kind request to dear Professors Bozzi, Carvalho and Zhu : Would you mind allowing me to download the slides of your three presentations ; Unfortunately I missed the whole presentation of  Mr Bozzi and most of Mr Carvalho’s presentation and I just joined you because I was with students !

  1. from Wenquan Che to everyone: 9:03 PM

One question is for Prof. Carvalho, for the body embedded mediccal devices, how to select the mostly appropriate frequency band for wireless power transmission, and how about the power transmission efficiency?  what is the biggest challenge of the wireless power charging for the body embedded medical devices or sensors etc?

  1. from Edoardo Carlini to everyone: 9:04 PM

about 5g, does it really make sense to make really any kind of device smart and connected? aren’t they just useless?

  1. from Syed Nazim Shah to everyone: 9:06 PM

Two questions for Professor Bozzi!

How to increase the gain of implantable medical devices? When the size is reduced the gain decreases.

Another question is about wireless power transfer, how to improve it?

  1. from Syed Nazim Shah to everyone: 9:08 PM

It’s difficult to get the circular polarization in implantable antenna. What are different techniques other than etching slots in the antenna, to get circular polarization at lower frequencies?

  1. from mahshid to everyone: 9:21 PM

thank you to all, and a question for Prof. Zhu , Iran is nationalizing the Internet, which means it is going to cut off the access of domestic users to the world. How long do you think developing such a technology will take from theory to implementation? I know it happened before in china

  1. from lsanogo to everyone: 9:24 PM

A question for Prof. Carvalho: As the RF signal brings not only information but also energy, how about its impact on human body and health, while embedded wearable devices and wireless communications continue to grow?

  1. from Elwalid Mohamed Elamin to everyone: 9:25 PM

Could you please inform me on how to join a career in the cellular mobile networks field with no previous experience and what are the different roles availabe there? More specifically for an international student in Europe, thank you.

  1. from Syed Nazim Shah to everyone: 9:27 PM

Prof. Bozzi!

How to implement slotted substrate integrated waveguide array for obtaining the cosec square pattern using Elliott’ Method for beamsteering?

  1. from Lirido to everyone: 9:28 PM

Greetings, I have a career development question. after finishing a BSC in ECE which Master degree is the best to further my knowledge in the microelectronics

  1. from Laboratory IMEP-LaHC – Grenoble, France to everyone: 9:31 PM

thank you for your presentation. I have a general question, if we use beamforming for all devices, will the RF harvesting still be an efficient approach?

  1. from Syed Nazim Shah to everyone: 9:33 PM

Two questions for Professor Bozzi!

How to increase the gain of implantable medical devices? When the size is reduced the gain decreases.

  1. from Syed Nazim Shah to everyone: 9:33 PM

  1. from Laboratory IMEP-LaHC – Grenoble, France to everyone: 9:35 PM

For Pr Carvalho: is the Backscattered RF system (with battery free remote control / passive) needing more power at the emitter/receiver station, compared to “standard” battery remote control ?

  1. from Pouya Mehrjouseresht to everyone: 9:36 PM

Hello, Thank you so much. I have a question from Prof. Nuno. Do you think which aspects of transmitters in a WPT system can play more important role to realize a sutainable and high performance system (based on backscattering, SWIPT)? Thank you so much.

  1. from Laboratory IMEP-LaHC – Grenoble, France to everyone: 9:36 PM

What about radars (for automotive) ? Any improvement/new ideas ?

  1. from Vesel Cemil ÇOLAK to everyone: 9:40 PM

I have a question to Carvalho & Zhu. Where the optical communications stand in terms of power efficiency, better or worse  in comparison to RF systems?

  1. from Laboratory IMEP-LaHC – Grenoble, France to everyone: 9:45 PM

When it comes to focused beams, would you think they could be used for powering implants, and if so how can we deal with undesirable stimulations? (biological thermal, SAR)

  1. from Laboratory IMEP-LaHC – Grenoble, France to everyone: 9:49 PM

Do you think we should restrict the 5G usage to only specifics domains that needs high speed data rate and not for “basic” communications ?

  1. from Jalil A. Rashed Mohassel to everyone: 9:52 PM

In  5G , we will have a EM polluted environment. Which body will monitor or control the level of pollution globally?

  1. from Wenquan Che to everyone: 10:00 PM

5G does not mean only the high speed, but also the wide coverage similarly needed in 4G.

Active engagement from Region 9: A total of nine ambassadors are confirmed and contributed to the DMI workshop promotion

Questions discussion among the students and DMIs (Selected from the chat history, many were asked and answered by direct conversation):

Q1 – Samad Atta    All Participants      do you think it will ever be possible for large structures like homes to be wirelessly powered?

Q2 – Discussions on “The students at UCF who do well in microwave courses are very popular on the job market. It is true at other universties.”

Q3 – do you think classical topologies based on copper and FR4 materials will eventually be replaced by optical interconnects or by nano-wires or graphene materials?

Q4 – What is the recommended certificates for fresh telecommunications engineering graduates?

Q5 – one main challenge is to provide power to a system without impacting or interfering with the performance of nearby systems as well as that system’s internal components. Is the advancement of wireless charging limited by interference with existing technologies.

Q6 – Can the digital predistortion work with envelop tracking PA supply which needs the precise envelop information ?
