Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Pseudo- High Order Wire Antenna Solvers

Abstract: We discuss our recent work concerning the evaluation of the current induced on thin wire antenna structures either by an incident field (the receive problem) or by a source located on the wire (the transmit problem). Our previous methods have been extended to accommodate arbitrarily large arrays of non-intersecting wire segments with a current source located on an array element. We also discuss our recent work in computational methods to accurately model the current in a neighbourhood of the source -- a long-standing difficulty in wire antenna modeling. We illustrate the performance of our solvers by considering an array of several hundred wire elements. Near and far-field results are efficiently extracted along with other quantities of interest such as the antenna gain. With Oscar Bruno, Caltech.
