Bandwidth and directivity enhancement of metamaterial-loaded loop antennas for microwave imaging applications
(Institute of Electrical and Electronics Engineers Inc., 2017)Compact, wideband and unidirectional loop antennas are presented, that are based on a conventional planar loop antenna that is loaded in a mu-negative (MNG) fashion with series capacitors, enabling a mu-zero (MZR) resonance ...

Compact EBG-Backed Planar Monopole for BAN Wearable Applications
(2017)This paper presents a planar monopole backed with a 2 × 1 array of electromagnetic bandgap (EBG) structures. The reflection phase of a single EBG unit cell has been studied and exploited toward efficient radiation of a ...

Compact, linear, lead/lag phase shifters using negative refractive index metamaterials
(2003)A new type of phase shifter using cascaded sections of NRI metamaterials and PRI transmission lines is proposed, which offers some significant advantages over conventional delay lines. The phase shifter is compact in size, ...

The effect of flow rate, head position, and inhaler orientation on the airflow and particle deposition in an mri-based mouth-throat geometry
(International Symposium on Turbulence and Shear Flow Phenomena, TSFP10, 2017)The mouth-throat plays a key role in the administration of inhaled medicines. It is an area of intense filtration, where an unacceptably high fraction of the released drug dose is deposited and thus wasted. Due to the ...

The method of fundamental solutions for the inverse conductivity problem
(2010)In this article, we propose a simple method for detecting an inclusion Ω2 embedded in a host electrostatic medium Ω1 from a single Cauchy pair of voltage and current flux measurements on the exterior boundary of Ω1. A ...

A multiband monopole antenna with an embedded reactance-cancelling transmission-line matching network
(2010)A series reactance-canceling (SERCA) transmission-line (TL) matching network is proposed, which replaces the series resonant circuit of a double-tuned Wheeler matching network with a λg/2 TL in order to achieve a broadband ...

Primal and dual problems in electrical impedance imaging
(2005)Ill-posed inverse boundary value problems are usually approached as problems of inference under a given set of boundary observations. The parameters and data are modelled as random variables so that to encompass the ...

Reconfigurable Bandwidth Bandpass Filter with Enhanced Out-of-Band Rejection Using π-Section-Loaded Ring Resonator
(2018)A novel ring resonator bandpass filter with reconfigurable bandwidth with central frequency at 2.4 GHz is demonstrated. Theoretical analysis for computing the resonant frequencies is shown, and the design approach of ...
