Superlinear

Superlinear was a group exhibition of 2D and 3D works curated by Jenna Baldock. This exhibition was held at Spiro Grace Art Rooms from June 11 - July 4, 2015. My contribution to the group show was a harmonograph (drawing machine) entitled The Forces of the Earth and two digitally edited drawings (enlarged and printed) that were originally produced on the harmonograph. The work inherently explores the movement and gesture of line independent from the human body, although not abstract from experience. My work discusses the experience of the body, more specifically my body; the pulsing of circulation; the rhythm of breathing; the twitching and trembling of muscles; the sound of the nervous system ringing in my ears. The pendulation of the line in motion corresponds to the body's extension into the world and the constant flow of energy; the weight of gravity, centripetal and centrifugal forces, and orbital oscillations. As the line dances acros the page the harmonograph parallels these peripheral sensations beyond the body.

Electronically-reconfigurable horizontally polarized wide-band planar antenna

Antennas are a necessary and critical component of communications and radar systems, but their inability to adjust to new operating scenarios can sometimes limit the system performance. Reconfigurable antennas capable of radiating in only specific desired directions can ameliorate these restrictions and help to achieve increased functionality in applications like direction finding and beam steering. This paper presents the design simulation, fabrication and measurement of a wide-band, horizontally polarized, direction reconfigurable microstrip antenna operating at 2.45 GHz. The design employs a central horizontally polarized omnidirectional active element surrounded by electronically reconfigurable parasitic microstrip elements, controlled by PIN diodes acting as RF switches. Experimental results show that the reconfigurable antenna has a bandwidth of 40% (2-3 GHz), with 3 dB gain in the desired direction and capable of steering over the 360° range.
