A 3D full-wave approach, based on the Foldy-Lax multiple scattering equations, is successfully extended to model massivelycoupled multiple vias using differential signaling and shared antipad in high speed vertical interconnects. For the first time, this method has been used and tested on via-pair with shared antipad in multilayered structure. The magnetic frill current source on the port is ca...

In this paper Microstrip antenna using semicircular patch is proposed and ANTENNA DESIGN simulated using HFSS software strip feed is used. microstrip antenna design is to increase the bandwidth and gain (1-14). performance analyses using high frequency structure simulator (HFSS) software. I'm starting with the calculation of design parameter using MATLAB. to get better. patch antenna was analyz...

This paper uses the accurate and computationally efficient complex image technique (CIT) to find the electric field and SAR distributions inside a human head illuminated by a finite-length dipole. The human head model used consists of 3 planar layers of lossy dielectrics. The accuracy of the results is verified by comparison with HFSS software. It was found that the CIT requires about 1 minute ...

data envelopment analysis (dea) with considering the best condition for each decision making unit (dmu) assesses the relative efficiency for it and divides a homogenous group of dmus in to two categories: efficient and inefficient, but traditional dea models can not rank efficient dmus. although some models were introduced for ranking efficient dmus, franklin lio & hsuan peng (2008), proposed a...

In this paper a study of the directive gain enhancement obtained using a dielectric lens placed in the near field of radiating elements is discussed. The design and results of a single element patch antenna along with hemispherical and spherical lens radiating in C-band are detailed. The design has been accomplished using the 3D finite-element-method (FEM) electromagnetic EM simulator, HFSS, is...
