The complex dielectric constants of building materials are present in the reflection, transmission and diffraction coefficients of the ray tracing formulation. Any deviation of the dielectric constants included in ray tracing simulation from the actual material properties may be a source of inaccuracy of the simulation results. This paper explores the sensitivity of ray tracing results to the inaccuracy...
As an emerging antenna concept, reconfigurable sensing antennas (RSAs) are presented in this paper. In order to clearly demonstrate the RSA concept and its operation principle, three RSA designs that use different sensing mechanisms for temperature sensation are proposed. Three temperature-sensing materials: water, high density poly-ethylene-Ba0.3Sr0.7TiO3 (HDPE-BST), and mercury, are integrated into...
