C. Zhao, An Efficient Design Method for Band-Pass Post Filters in SIW Technology and the losses Analysis, 3rd December 2015

  Abstract: The characteristics of cylindrical post arrangements in the cross section of rectangular waveguides can be analyzed accurately and quickly with mode matching technique. Based on this technique, an efficient design approach for band-pass post filters in Substrate-Integrated Waveguide (SIW) technology will be introduced in this presentation. In addition, in order to investigate the […]

S.J. Chen, Highly efficient and flexible antennas realized in conductive polymers, 13th August 2015.

  Abstract: Since the initial report of electrical conductivity in polymer materials in 1977, conductive polymers have been developed with steadily improving electrical conductivity and mechanical flexibility. Despite the challenges of simultaneously achieving sufficient thickness and satisfactory conductivity, they can be now considered as a new class of promising conductive materials for conformal applications which […]

Research Seminar Monday 2nd December, Biomedical Applications of Terahertz Technology

Abstract: Early experiments by pioneers of THz imaging demonstrated that the technique could have a variety of applications, including medicine and dentistry – terahertz images of bacon showed contrast between lean meat and fat; changes in refractive index of teeth at THz frequencies allow for the detection of early decay. Since then there have been […]

Research Seminar 28th November – Time-Domain Meshless Methods in Electromagnetics

Abstract: Computational Electromagnetics is the science of numerically solving a complex set of Maxwell’s equations using limited computer resources. Electromagnetic simulations have become indispensable for designing of many devices such as radars, computer chips, mobile phone systems, etc, however there is still need for versatile method to address complex problems. Meshless methods are a new […]

Research Seminar 21st November – Metamaterial-Inspired Structures and their Applications in Microwave, Millimeter-wave and Terahertz Planar Circuits

Abstract: Metamaterials are composite structures that are engineered to modify the electromagnetic properties of materials. The concept of metamaterials is especially useful in order to achieve new physically realizable responses that may not be readily available in nature. The key to the application of metamaterial resonators for the synthesis of such effective media is their […]

Research Seminar 14th November – Impacts of IEC61850-9-2 Samples Loss and Frame Size on Total Vector Error of an Estimated Phasor

Abstract: The concept of utilizing Phasors in computation of power quantities dates to 1916 when Proteus Steinmetz published a paper on a mathematical technique for analysing AC networks. The Phasor has been firstly defined and codified in the IEEE 1344 which has been later voted as IEEE C37.118 standard in 2005. In this standard, the […]

Research Seminar 15th November – Sensitivity based Image Filtering for Multi-Hashing

Abstract: Hashing is an effective method to retrieve similar images from a large scale database. However, a single hash table requires searching an exponentially increasing number of hash buckets with large hamming distance for a better recall which is time consuming. The union of results from multiple hash tables (multi-hashing) yields a high recall but […]

Research Seminar 7th November- Contactless measurements of vital signs

Abstract: Clinically used methods to derive vital signs such as heart rate and respiration use electrodes, optical or mechanical sensors, which must be attached to the body. Innovative systems, however, allow for low-contact or even contact-free measurements of vital signs. Amongst others, the capacitive electrocardiogram, camera-based and radar-based measurements have been proven to be applicable. […]

Research Seminar 5th November- Beyond von-Neumann architectures: Scalable neuromorphic hardware

Abstract: Biological neural systems outperform the most advanced computing machines in solving nondeterministic, highly complex and multi-dimensional tasks. Performing such tasks in real-time needs extremely complex classical (von Neumann) computing machines, and hence, rendering them impractical. In contrast, biological neural systems autonomously process information in complex environments by learning features and associations. Since real world […]
