Input impedance of a slot-cylinder antenna
… conductance is obtained for a finite slot. The phase constant, which is contained in the expressions for the line parameters, is a function of the line parameters. Thus, a final answer requires the solution of simultaneous equations. This is done on a digital computer. This analysis applies to …

Planar groove gap waveguides
… of the transmission line loss and phase constant for PGGWG at Ka-band shows that PGGWG has comparable attenuation over the band of interest to SIW. The transmission line Q-factor is found to vary from 135 to 140 over the band of interest, which is comparable to SIW in the same …

Behavior of low-frequency sound waves in porous media
This is a study of the relationship between the measured acoustic parameters and the measured physical parameters of porous media. Materials studied include crushed limestone, stream-formed pea gravel, large and small sifted pea gravels, and glass spheres. A standing wave curve fitting algorithm …

Modelling of Electromagnetic Surface Wave Propagation for High-Speed Communications
… on the electromagnetic field to determine the phase constant of the supported surface wave. The results of the model are consistent with numerical solutions using the COMSOL software package and with experiments. Next, surface waves on uniform two-wire and multi-conductor systems are studied. …

Scaling of entanglement entropy in some condensed matter systems
… Chapter 3 studies the many-body localization phase transition in a Rokhsar-Kivelson type wave function. Chapter 4 studies the subleading correction term of entanglement entropy in 2+1 dimensional scale invariant systems. Chapter 5 studies the bulk-boundary correspondence in 3 + 1 dimensional …
