    The purpose of this review paper is to critically examine some the physics-based fundamental limitations. Using metamaterials and/or other exotic physical phenomena for performance. This, in turn, prompts us to critically examine the effective medium theories, and rigorously model the physical structures that show promise rather than their effective medium equivalents to see if indeed their actual...

    On-body communication channels are used in an increasing number of applications, including headsets and wristwatch controllers for mobile phones, and systems for emergency personnel and for personal medical support. In channels for such systems, at ISM band frequencies, the movement of the body causes significant fading, in addition to that caused by scattering from the local environment. Statisti...

  • Understanding on-body fading channels at 2.45 GHz using measurements based on user state and environment

    Cited by:  Papers (7)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (175 KB) | HTML iconHTML

    This paper discusses the nature of small scale narrowband fading in on-body propagation channels based on a systematic experimental campaign at 2.45 GHz. In particular, we use the Nakagami-m distribution to provide insight into the effect of both user state and local environment on channel characteristics. Nakagami-m parameters were much greater than 1 when the user was stationary, irrespective of... View full abstract»

    An antenna fabricated using clothing materials is presented. The antenna operates over the wireless network bands at 2.45 Hz and 5 GHz. An electromagnetic band gap surface is used to reduce back radiation by 10 to 15 dB while maintaining the impedance match over the two frequency bands. Coupling between antennas is significantly reduced making it ideal for body worn communication systems. View full abstract»

    This paper chronicles the progress in wireless information transmission and reception, and discusses future trends in radiowave propagation research. Since the conception of wireless transmission, a number of pioneers have successfully understood and characterised the behaviour of narrowband, wideband and ultra-wideband signal transmission in a variety of environments and spectral regions. The phy... View full abstract»

    This contribution describes recent progress towards a functioning UWB radar system for imaging the human breast. The antenna and array design are described and a typical phantom result is presented herein. The project is currently conducting clinical trials and images from these trials will be presented at the conference, along with many more phantom images. View full abstract»

    Small antennas have been widely investigated and reported in various medical applications for some times. It is interesting to note that small ultra wideband (UWB) antennas are also demanded for some medical applications recently. One of the medical applications which require the UWB antennas is the microwave imaging of breast cancer. This imaging modality transmits lower power short microwave pul... View full abstract»

  • Direct detection of the magnetic fields of neuronal impulses using MRI

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (142 KB) | HTML iconHTML

    The neuronal (ionic) current caused by nerve firing induces subtle and transient magnetic flux density changes that potentially modulate the MR signal over successive gradient echo planar image frames. Frequency spectra derived from Fourier transformation of experimental data down these time frames show evidence of a strobe stimulus localized to regions containing the optic nerve and visual cortex...

    In the 1980's new requirements were issued to make airframes meet criteria for low radar cross-section characteristics. These requirements simultaneously created a need for improvement of radar cross-section measurement techniques to validate the performance of the designs. Thus was the advent of the modern technologies of short pulse instrumentation radars, specially designed outdoor RCS ranges, ... View full abstract»

    Planar spiral resonators on the conductor backed substrates are examined in the view of metamaterial, compact antenna and System-in-Package applications. A single layer spiral and stacked tightly coupled spiral resonator pairs on the conductor backed substrates have been investigated. It is shown that rotation of the spirals with respect to each other in a pair results in decrease of the resonance... View full abstract»

    This paper reports an experimental investigation of split-ring and wire negative refractive index media. Negative refractive index effects were demonstrated, but the sample showed strong non-specular scattering from irregularities in its structure. We also report an extension of bandwidth limitations on artificial magnetic conductor surfaces to oblique incidence, and a brief examination of negativ... View full abstract»
