An approach for transmitting multiple signals using a single switched parasitic antenna (SPA) has been recently reported. The idea there is to map the signals to be transmitted onto a set of basis functions that serve as “virtual antennas” in the beamspace ...

In this thesis we study the properties of optical wire antennas. As experimental method for our investigations we use apertureless near-field optical microscopy. This technique achieves high spatial resolution well beyond the diffraction limit by utilizing ...
This letter explores the impact of quantum well placement and photonic crystal (PhC) etch depth on the emission directionality of thin-film InGaN PhC light-emitting diodes (LEDs). The far-field pattern of 800-nm-thick PhC LEDs is tuned by varying only the ...
We present near-field measurements of optical Yagi-Uda nanoantennas that are used in receiving mode. The eigenmode imaging of amplitude and phase by apertureless scanning near-field optical microscopy allows us to investigate the dynamics of the local out- ...
The effect of substrate permittivity on UWB antenna radiation is studied. Microstrip and CPW-fed UWB monopoles are designed using substrates with different dielectric constants. The radiation patterns are measured. The transfer function of a two identical ...

Re-configurability is one of the key features in modern wireless communications. Indeed, the increase of services provided imply an optimized management of the electromagnetic spectrum, along with strong miniaturization in order to allow for the cohabitati ...
Radio frequency identification (RFID) is an exciting, rapidly growing, multi-disciplinary field with emerging technologies and applications. Today RFID is a generic term for technologies that use radio frequencies to automatically identify people or object ...
Since the introduction of implantable pacemakers in the early 1960s, implantable medical devices have become more and more interesting for healthcare services. Nowadays, the devices designed to monitor physiological data from inside the human body have gre ...
The study of the lightning interaction with tall strike objects has attracted considerable attention of lightning researchers lately. Many lightning measurements including current and associated electromagnetic fields were recently made all over the globe ...
