Microwave holograms and microwave reconstruction
Electronics Letters, 1969 Microwave holographic reconstruction of the metal objects inside a purse was achieved by a nonscanning method. A microwave field was used for both constructing and reconstructing the holographic image. The visualisation of the microwave field was performed by both Polaroid and liquid-crystal techniques. The frequency used was 34.26GHz.

Lithographic technology for microwave integrated circuits
, 1997 Conductive lithographic films (CLFs) have been developed primarily as substitutes for resin/laminate boards, which share properties with the metallisation patterns used in planar microwave integrated circuits (MICs).

A linear inverse space mapping algorithm for microwave design in the frequency and transient domains
, 2004 An inverse space mapping optimization algorithm for designing linear and non-linear microwave circuits is presented in this work for the first time. The inverse space mapping follows a piece-wise linear formulation, avoiding the use of neural networks.

Gain enhancement wideband CPW antenna based on artificial magnetic conductor
Scientific ReportsUnidirectional radiation and, hence, gain enhancement can be achieved by placing a primary radiator (simple antenna) at suitable height over a reflector to diminish back radiation and to enhance the forward radiation.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Microwave workshop for windows
Computers & Education, 1995 A suite of three programs has been developed to support the teaching of microwave theory and design. A secondary function of the package is to support microwave engineers by providing a library of utilities to assist their design function. All three programs were written in Visual Basic and are aimed at supporting both tutor-directed and student ...

Investigation of microwave antennas in lossy media for medical applications
For several years, microwave engineers have dreamed of using non-ionising electromagnetic waves in medical imaging applications. The rate of evolution of microwave techniques for medical application has been immense and shows no signs of relenting. Since

Distortion mechanisms in varactor diode-tuned microwave filters
, 2006 This paper examines the broadband distortion behavior in flexible filters employing varactor-diode tuning elements. Series- and parallel-resonant varactor-loaded transmission-lines, both commonly used in bandpass and bandstop microwave filters, are ...
