Article
The robust design of microwave, millimeter-wave, or Terahertz components and structures incorporating manufacturing process tolerances would enhance the fabrication yield and thereby reduce the overall production cost. Based on the spectral stochastic finite element method (SSFEM) for material variations, a novel geometrical SSFEM (GSSFEM) is propo...
Article
The impact of fabrication uncertainties such as random variations in material properties of the media on the electromagnetic system response are usually ignored due to computational cost. This was evaluated in this study using a spectral representation of these random parameters. The finite element formulation for electromagnetics with edge element...

Article
The hemisphere lens-loaded Vivaldi antenna for the microwave imaging applications is designed and tested in this paper. The proposed antenna is designed to work in the wide frequency band of 1–14 GHz, and is fabricated on the FR-4 substrate. The directivity of the proposed Vivaldi antenna is enhanced using a hemispherical shape dielectric lens, whi...
Conference Paper
Microwave imaging of dielectric media plays a major role in non-destructive testing, remote sensing, medical imaging etc. The procedure usually requires the measurement of reflection coefficient data of the object under test in free space over a wide frequency band which demands an ultra-wide band antenna. The design of a UWB antipodal Vivaldi ante...
