Optical modulation of continuous terahertz waves towards cost-effective reconfigurable quasi-optical terahertz components

Creator:: Cheng, Li-Jing and Liu, Lei
Abstract:: We report optical modulation of continuous terahertz (THz) wave in the frequency range of 570-600 GHz using photo-induced reconfigurable patterns on a silicon wafer. The patterns were implemented using programmable illumination from a commercially-available digital light processing (DLP) projector. A modulation depth of 20 dB at 585 GHz has been...

Photo-induced spatial modulation of THz waves: opportunities and limitations

Creator:: Kannegulla, Akash, Bin Shams, Md. Itrat, Liu, Lei, and Cheng, Li-Jing
Abstract:: Programmable conductive patterns created by photoexcitation of semiconductor substrates using digital light processing (DLP) provides a versatile approach for spatial and temporal modulation of THz waves. The reconfigurable nature of the technology has great potential in implementing several promising THz applications, such as THz beam steering, THz imaging or THz...

Local scour at isolated obstacles on river beds

Creator:: Huang, Cheng-Chang
Abstract:: Maximum equilibrium scour depths, equilibrium scour volumes, and induced equilibrium movements at isolated obstacles on river beds were investigated in clear-water scour. The research was achieved by a systematic flume study based on the results of dimensional analysis of local scour. The main tested obstacles for local scour were cubes....

Learning control of linear systems with periodic inputs using a method of harmonic analysis

Creator:: Cheng, Sih Yao
Abstract:: This paper describes a learning control system which is capable of controlling a linear plant subjected to periodic inputs, providing that an upper limit for the order of the plant is known. Otherwise the characteristics of the plant and the inputs are unknown. Only one system variable is measured. The...

Determinants of consumer behavior toward counterfeit products: involvement and the attitude toward brand equity

Creator:: Cheng, Yu-Chi
Abstract:: Counterfeits, unauthorized copies of a product presented for sale as if they were the legitimate manufacturer's product, are creating a sizeable and growing problem for the apparel and accessory industries (Olsen & Granzin, 1993). The purpose of the study was to investigate the relationship between consumers' likelihood of knowingly purchasing...

Environmental influences on monoterpenes and phenolics of Mentha piperita

Creator:: Yao, Cheng C.
Abstract:: Vegetatively propagated peppermint (Mentha piperita L., cv. Black Mitcham) was used to determine the effects of night temperatures (8°C vs 25°C) on the plant growth in terms of fresh weight and leaf area, and on metabolite contents. The plants were sampled after 14 days, 21 days and 28 days in...

Growth, physiological characteristics and plasmid profiles of Bifidobacterium species

Creator:: Cheng, Ronshan
Abstract:: The fecal flora of healthy bottle or breast-fed infants was examined for the presence of Bifidobacterium. Identification was based on the presence of fructose-6-phosphate phosphoketolase, which is found only in these bacteria. No bifidobacteria were recovered from bottle-fed infants. However, bifidobacteria were readily isolated from 15 day to 3 month...
