New configurations for RF/microwave bandstop and lowpass filters

Creator:

Peddibhotla, Harish V.

Abstract:

This thesis presents new, compact configurations for RF/microwave bandstop and lowpass filters for embedded passive applications. A simple design methodology is presented for designing the folded-transmission line filters on a microstrip platform. Unlike the conventional stub-loaded filter designs, the proposed folded-line filters will have practical dimensions for a wide range...

A direct-drive wave energy converter with contactless force transmission system

Creator:

Agamloh, Emmanuel B.

Abstract:

Commonly proposed ocean wave energy converters (OWEC) use inefficient and maintenance demanding intermediate hydraulic and pneumatic systems. We propose a novel rotary direct-drive OWEC that eliminates these intermediate stages. The new device employs a contactless force transmission system (CFTS) comprising a “piston” and a “cylinder” and a ball screw to...

Dissertation
A test fixture and deembedding procedure for high-frequency substrate characterization

Creator:

Webb, Kyle M.

Abstract:

At frequencies exceeding 1-2 GHz, the substrate network models used in substrate coupling simulation must account for the reactive nature of the substrate. Unlike at low frequencies, where the purely resistive substrate models can be validated through DC resistance measurements, these high-frequency models, comprising reactive components, must be validated through...
