Abstract

With the world wide adoption and access to voice and data through Long Term Evolution (LTE) services, the cellular industry is now the world's largest innovation engine. For most parts of the world mobile is the leading internet access platform for internet access. Today there are 4.5 billion worldwide mobile subscribers with this number expected to reach 6 billion by 2020. The workshop examines the current status of LTE RF Front End Modules and the ways it evolve to deliver a gigabit-per-second user experience which is the LTE 5G goal. 5G is simultaneously an evolutionary process (LTE evolution) with few elements of revolution (5G New Radio NR). There are three LTE advanced techniques to increase the data rate for 5G which will be explained in this workshop such as:
  - Wider bandwidth via carrier aggregation
  - Higher order modulation
  - MIMO utilization

5G ecosystem will consist of two frequency area of interest: sub 6GHz frequency domain and mmWave spectrum. Both areas will be covered by this workshop as well the technologies used. Both 4G LTE as it currently used and 5G NR will be deployed concurrently in spectrum below 6GHz and therefore standalone 5G will not be deployed in LTE bands for a while. To increase the data bandwidth there is also the need to increase the capacity for backhaul network.

Most of the recent 5G headlines have been focused on mmWave spectrum and the introduction of the new techniques like beam forming which will be presented in this workshop. Currently there are many technical challenges that would prohibit mmWave deployment in consumer devices as a first step in the 5G technology roadmap, but will be initially deployed for wireless backhaul solutions.

Abstract

Terahertz (THz) electromagnetic waves, which are located between microwaves and light (from around 0.1 THz to 10 THz), are attracting much attention in interdisciplinary fields straddling electronics and photonics. A wide variety of THz-wave applications are being developed, including high-data-rate wireless communication and high-resolution sensing. THz sources are the most important components in developing advanced THz applications because the sources can be the limiting factor of the performance of application systems. Performance indicators of interest include the operation frequency, output power, power consumption, size, complexity, tunability and cost. Among others, solid-state semiconductor-based sources are highly promising for various applications and are rapidly being developed around the world.

In this Workshop on "Recent progress of terahertz sources for advanced applications", six distinguished invited speakers will present solid-state THz sources using different mechanism and materials including a multiplier based on Schottky barrier diodes (SBDs), integrated circuits based on high-electron-mobility transistors (HEMTs) using III-V compound semiconductors , silicon-based complementary metal oxide semiconductor (CMOS) circuits, resonant tunneling diodes (RTDs), quantum cascade lasers (QCLs), and photodetectors (PDs). After the invited talks, we will hold an open discussion with all the presenters and participants on the future direction of the field and any further points.

Abstract

The Near-Field Wireless Power Transfer (WPT) techniques has found extreme usefulness in this decade. It can be due to multiple low power sensor type potential applications as a wireless power supply system for implants, body area networks, drug delivery systems, etc. In this context, there has been strong emphasis on DGS-based WPT systems owing to the superior performance and ease of their design when compared to the conventional coil based WPT systems. This workshop will take the audience through the challenges and solutions related to DGS structures and their incorporation in single band and dual-band WPT systems. Simultaneously RF energy harvesting has also attracted attention for application scenarios such as power transfer to the sensors used in patient health monitoring, the sensors in hazardous environment, and the sensors for covert security operations. The matching network and highly efficient rectifiers are extremely critical to develop a successful energy harvesting system. In this workshop, the audience will be introduced to the recent advances in multi-band and wideband impedance matching techniques and the promising diode-based and PA-based rectifier configurations.

Abstract

A Wireless Power Transfer technologies are developed in US, EU, and Japan mainly in 20th century. However, after a revolution of the WPT by proposal of a resonance coupling WPT by MIT group, there are a lot of interesting research and development of the WPT in the world. Recently, Asian activities of the R&D of the WPT is very active, not only in Japan but also in various Asian countries. For example, a lot of commercial electric buses supported by an inductive wireless charging system run in many Chinese cities. In Korea, they are promoting OLEV (On-Line Electric Vehicle) and inductive WPT aided train system. In China, some group carried out a microwave beam WPT experiment and designed a Solar Power Satellite with the beam microwave power technology. Singapore's group propose and is developing medical system with a microwave power. In Vietnam, they are interested in the microwave power transfer system. Recently Japan leads a collaboration of Asian countries to promote the WPT R&D via scientific society of IEICE, which is named Asian Wireless Power Transfer Workshop. There are deep discussion toward new regulation of the WPT, not only an inductive WPT but also a WPT via microwave in China-Japan-Korea collaboration. The result of the discussion is submitted to ITU (International Telecommunication Union) to establish new WPT regulation. So recent hottest region of the WPT R&D in the world is Asia. In this workshop, we focus on the novel WPT technologies in Asian countries and regulation/standardization status from the Asia.
