Abstract:
Split ring resonator (SRR) is a metamaterial structure which displays negative permeability values over a relatively small bandwidth around its magnetic resonance frequency. Unit SRR cells and arrays have been used in various novel applications including the design of miniaturized microwave devices and antennas. When the SRR arrays are combined with the arrays of conducting wires, left handed materials can be constructed with the unusual property of having negative valued effective refractive indices. In this thesis, unit cells and arrays of single-ring multiple-split type SRR structures are

Abstract:
Batteries have imparted momentum to the process of transition towards a green future. However, mass application of batteries is obstructed due to their explosive nature, a trait specific to Li-Ion batteries. To cater to an efficient battery utilization, an introduction of a battery management system would provide an ultimate solution. This thesis deals with different aspects crucial in designing a battery management system for high energy as well as high power applications. To build a battery management system capable of predicting battery behavior, it is necessary to analyze the dynamic proce

碩士<br>國立雲林科技大學<br>電子工程系<br>107<br>In this thesis, the silver reference electrodes and conductive wires were printed onto a polyethylene terephthalate substrate (PET) by using screen printing technology. Next, aluminium-doped zinc oxide (AZO) or zinc oxide (ZnO) was deposited onto the silver electrodes by using the vacuum radio frequency (RF) sputtering system. The enzyme like glucose oxidase (GOx) or ascorbate oxidase (AO) was immobilized on the AZO or ZnO membranes to fabricate the glucose biosensor or the ascorbic acid biosensor, respectively. After that, graphene oxide (GO) and magnetic bea

碩士<br>國立交通大學<br>電子研究所<br>107<br>In this thesis, an extensive investigation has been carried out on the layout dependent effects in multi-finger (MF) and multi-ring (MR) nMOSFETs, and the impact on high frequency performance like most importantly unit gain cut-off frequency fT and maximum oscillation frequency fMAX, as well as RF noise in nanoscale CMOS technologies. A comprehensive extraction flow has been developed for accurate determination of the intrinsic device parameters as well as intrinsic parasitic resistances, inductances, and capacitances (RLC), which are key parameters governing fT

Abstract:
<p>Due to increasing regulation on emissions and shifting consumer preferences, the wide adoption of battery electric vehicles (BEV) hinges on research and development of technologies that can extend system range. This can be accomplished either by increasing the battery size or via more efficient operation of the electrical and thermal systems. This thesis endeavours to accomplish the latter through comparative investigation of BEV integrated thermal management system (ITMS) performance across a range of ambient conditions (-20 °C to 40 °C), cabin setpoints (18 °C to 24 °C), and six different

Abstract:
Yes<br>This paper investigates the interaction phenomena of the coupled axons while the mutual coupling factor is presented as a pairwise description. Based on the Hodgkin-Huxley model and the coupling factor matrix, the membrane potentials of the coupled myelinated/unmyelinated axons are quantified which implies that the neural coupling can be characterised by the presented coupling factor. Meanwhile the equivalent electric circuit is supplied to illustrate the physical meaning of this extended model. In order to estimate the coupling factor, a data-based iterative learning identificatio

碩士<br>國立雲林科技大學<br>電子工程系<br>107<br>In this thesis, the dye-sensitized solar cells (DSSCs) were fabricated on fluorine doped tin oxide (FTO) glass or flexible indium tin oxide/ polyethylene terephthalate (ITO/PET). The photoanode was double layer structure. Firstly, we deposited the Al-doped zinc oxide (AZO) seed layer on FTO glass by sputter system and then grew the zinc oxide (ZnO) nanorods on the AZO seed layer by hydrothermal method. Finally, we deposited the titanium dioxide (TiO2) on ZnO nanorods by the doctor blade method, the photoanode had been finished. The ZnO nanorods could increase
