Weekly Seminar: “GAL – Galileo for Gravity”

ABSTRACT: GAL project aims the study and development of a state-of-the-art methodology for the determination of precise and high-resolution gravity field models. The key issue is the precise Kinematic Airborne Gravimetry (KAG), with the joint use of most recent techniques and technologies, such as EGNOS, GPS, Galileo and strapdown Inertial Measurement Units (IMUs), and its [...]

Weekly Seminar: “Wireless power transfer and energy harvesting for RFID”

ABSTRACT: RFID technology provides a foundation, an enabling technology towards the realization of ‘zero-power’ wireless sensors and implementing the Internet-of-Things (IoT) and machine-to-machine (M2M) communication. The presentation begins with an overview and state-of-the-art in commonly used energy harvesting technologies such as solar, vibration, thermal and electromagnetic. Special focus is placed on challenges associated with electromagnetic [...]

Weekly Seminar: “From Time-Reversal Mirrors to Tunable Metasurfaces”

Speaker: Prof. Mathias Fink

ABSTRACT: Time-reversal invariance is a very fundamental concept in physics. The objective of this talk is to show how this concept can be turned into a huge source of innovations and successful start-up companies. It was first in the field of acoustics and later for microwaves, where antenna array technology was available, that “time-reversal mirrors” [...]

Weekly Seminar: “The experimental study of microwave power transmission and active energy harvesting”

Speaker: Prof. Shigeo Kawasaki

ABSTRACT: Researchers around the world have started developing green wireless energy/power technology, focusing on environmental issues, human–nature interactions and cost-effectiveness. This technology is called as “the wireless energy transfer and conversion”. In the presentation, the wireless green-eco technologies by microwave technology and the category of wireless power transmission and energy harvesting were introduced. Components and [...]

Weekly Seminar: “EURASIP Seminar: Parameter estimation and synchronization in digital satellite receivers”

ABSTRACT: In contrast to terrestrial communication systems, satellite-based solutions offer some remark- able benefits: they are quickly deployed, services are provided to equal costs within the whole coverage zone, and they form a key element for ubiquitous access on a worldwide level. Only via a satellite-based infrastructure one can connect isolated regions, like polar or [...]

Weekly Seminar: “Look bro! No hands! The experiences of the Geomatics division with Unmanned Aerial Vehicles”

17 September 2014 - 17 September 2014
Speaker: Pere Molina

ABSTRACT: Drones. That word, capable of evoking the worst fears to some of you -yet, also evoking some of our (the Geomatics division’s) best feelings and memories! Indeed, Geomatics and Unmanned Technology have come together since around thirty years now; so it is time to time to stop and look back to understand how they [...]

Weekly Seminar: “Radio-Frequency Nanoelectronics – Electromagnetics and Quantum Transport in Carbon Nanodevices”

ABSTRACT: In view to the new epochal scenarios that nanotechnology discloses, nanoelectronics has the potential to introduce a paradigm shift in electronic systems design similar to that of the transition from vacuum tubes to semiconductor devices. The aim of RF nanoelectronics is to close the gap between the nanosciences and a new generation of multifunctional [...]

Weekly Seminar: “Evolution Towards 5G Cellular Networks: Radio Resource and Interference Management Issues”

In the frame of the IEEE DL, the CTTC presents a new talk in the Weekly Seminars Series. ABSTRACT: 5G cellular wireless networks are expected to be a mixture of network tiers of different sizes, transmit powers, backhaul connections, different radio access technologies (RATs) that are accessed by an unprecedented numbers of smart and heterogeneous [...]

Weekly Seminar: “Green In-Building Optical-Wireless Networks”

ABSTRACT: Today, in-building networks consume only a small fraction of buildings’ total power consumption. However, their power consumption is directly proportional to their aggregate bit rate, and so grows exponentially every year. As a result, unless new “green” network technologies are developed, the networks’ energy consumption will dominate all other energy sinks (such as A/C, [...]

Weekly Seminar: “Multi-frequency Co-prime Arrays for DOA Estimation”

ABSTRACT: Co-prime arrays have found broad applications in both areas of radar and sonar. Co-prime arrays are two subarrays with co-prime elements and co-prime inter-element spacing. The equivalent co-array includes a large number of virtual elements, thus increasing the number of degrees of freedom and enabling direction of arrival estimations of a number of sources [...]
