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.

Performance study of automatic transmit power control (ATPC) in point to point microwave link for rain attenuation problem in Malaysia [PDF]

, 2006
Point-to-point microwave system is the backbone link for mobile communication industry as well as for other applications. In tropical region particularly in Malaysia, rain attenuation is the major constraint for implementing microwave system above 10GHz.

An EIRP Measurement Method of High-Power Microwave Systems Based on Near-Field Testing

International Journal of Antennas and Propagation
The equivalent isotropic radiated power (EIRP) of high-power microwave (HPM) systems is a core-evaluating indicator. In practical testing, locating a suitable test site for the far-field method becomes challenging due to the requisite antenna separation.

Gain enhancement wideband CPW antenna based on artificial magnetic conductor

Scientific Reports
Unidirectional 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.

Metamaterial enhanced sensor for powder material classification

Scientific Reports
In this paper, a simple and efficient approach is presented to classify different power materials based on a one port microwave sensor in X-band. This classification focuses on powder materials, unlike prior studies that focused on liquids (castor oil ...
