Hua, Xia (2010-10-12)Genetic algorithm is often used to find the global optimum in a multi-dimensional search problem. Inspired by the natural evolution process, this algorithm employs three reproduction strategies -- cloning, crossover and ...
-
Sekar, Vikram (2012-10-19)The main purpose of this dissertation was to address key issues in the design and analysis of RF/microwave filters for wireless applications. Since RF/microwave filters are one of the bulkiest parts of communication ...

Hsieh, Lung-Hwa (Texas A&M University, 2004-09-30)Microstrip ring circuits have been extensively studied in the past three decades. A magnetic-wall model has been commonly used to analyze these circuits. Unlike the conventional magnetic-wall model, a simple transmission-line ...
-
Jeong, Jaehoon (2009-05-15)An analytical solution for the coupled telegrapher’s equations in terms of the voltage and current on a homogeneous lossy transmission line and multiconductor transmission line is presented. The resulting telegrapher’s ...
-
Wu, Zuoguo (Texas A&M University. Libraries, 1993)The goal of this project was to investigate the kinetics of baculovirus-infected .insect cell cultures. The cell death process of baculovirus-infected insect cells was divided into two phases: a constant viability (or ...
-
Hummer, Kenneth Andrew (Texas A&M University. Libraries, 1994)Circular cylindrical cavity resonators have been studied in three configurations. First, a slot antenna backed by a circular cylindrical cavity was analyzed. The resonant frequency of the cavity is found using power ...
-
Long, Stephen A. (2010-07-14)This thesis presents the design, theory, and measurement of a linearly polarized microstrip patch antenna with a novel substrate-integrated mechanism that can compensate the detuning effects from a physical deformation. ...
-
Wang, Miao (2010-10-12)Nanochannel devices have been explored over the years with wide applications in bio/chemical analysis. With a dimension comparable to many bio-samples, such as proteins, viruses and DNA, nanochannels can be used as a ...
-
Kim, David G. (2010-10-12)Recent days, antennas play an important role in wireless communication system. Microstrip patch antennas are well known to have positive features for cost-effective, low profile and broadband. This type of antenna can be ...
-
Hsu, Shih-Hsun (2009-05-15)The reflectarray antenna has been considered as a suitable candidate to replace the traditional parabolic reflectors because of its high-gain and low-profile features. Beam scanning capability and multi-band operation are ...
-
Han, Chul Min (Texas A&M University, 2006-10-30)In recent years there has been a growing demand for reduced mass, small launch volume, and, at the same time, high-gain large-aperture antenna systems in modern space-borne applications. This dissertation introduces new ...
-
Gu, Minyu (2019-05-30)^31P MRS offers unique non‐invasive access to investigate the in vivo metabolism and is a significant advancement in the understanding and treating of many disease processes. The challenge of in vivo dynamic ^31P MRS mainly ...
-
Gu, Minyu (2022-11-22)This dissertation develops a general formulation and computational method to model the electromagnetic response of infinitely extended or arbitrarily shaped in-plane anisotropic conductive two-dimensional materials embedded ...
-
Pallampati, Sumana (2017-07-27)Origami (the art of folding) can be incorporated into antenna systems to provide compact size and low weight designs. Apart from this, the system can also provide physical reconfigurability and ease in deployment and ...
-
Cholleti, Vipin K. (2011-08-08)Due to the growth in mobile wireless systems, electrically small antennas (ESAs) which are efficient and have significant bandwidth are in great demand. But these requirements are contradictory. ESAs are known to be highly ...
-
Park, Kyongtae (Texas A&M University, 2005-11-01)A fiber optic system for measuring magnetic heading and pitch of one or more compass heads in a towed acoustic array has been developed as a cooperative effort between engineers at Fiber Dynamics, Inc., and faculty and ...
-
Park, Joohwan (Texas A&M University, 2006-10-30)Phase locked loops (PLL) are used in a variety of RF integrated applications because of their ability to generate precise clock signals. These applications include clock recovery systems, frequency synthesizers and frequency ...
-
Hsiao, Meng-Jie (2019-11-12)This research demonstrates two novel millimeter-wave (mm-wave) fully-integrated frequency-division duplexing (FDD) transmitting-receiving (TX-RX) front-end modules, including duplexer (DUX), power amplifier (PA), and low ...
-
Brown, David Gerald (Texas A&M University, 2007-04-25)Parallel magnetic resonance (MR) imaging may be used to increase either the throughput or the speed of the MR imaging experiment. As such, parallel imaging may be accomplished either through a "parallelization" of the MR ...
