The microwave industry has shown increasing interest in electronic ceramic material (ECM) due to its advantages, such as light weight, low cost, low loss, and high dielectric strength. In this paper, simple antennas covered by superstrate layers for 2.30 GHz to 2.50 GHz are proposed. The antennas are compact and have the capability of producing high performance in terms of gain, directivity, an...

Recent broadband modeling of regional events suggests that vertical directivity is particularly important at high frequency. Conventionally, such directivity is obtained by summing a grid of point sources. This relatively time-consuming procedure can be greatly reduced by introducing directivity time histories appropriate for the various crustal phases in terms of upgoing and downgoing paths th...

The perception of sound in architectural spaces is influenced by two main factors: the properties of the space in which the sound is produced, and the properties of the source producing the sound. This research project uses computational modeling to study the effect of these properties on the binaural response in a virtual space. Two independent parameters were studied: the scattering coefficie...
