Compact Orthomode Transducer with Broadband Beamforming Capability

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk

A compact and broadband orthomode transducer (OMT) with two dual linearly polarized ports is reported here for the first time. The component is based on a combination of two ridged Boifot junctions through a series of power dividers that act as an embedded ...

Four-Port Broadband Orthomode Transducer Enabling Arbitrary Interelement Spacing

Juan Ramon Mosig, Anja Skrivervik, Emile Jacques de Rijk, Tomislav Debogovic, Maria Garcia Vigueras, Santiago Capdevila Cascante, Esteban Menargues Gomez

This paper reports a novel methodology to design broadband orthomode transducers with two arbitrarily spaced ports carrying orthogonal linear polarizations. The component is based on a combination of two Boifot junctions through a series of power dividers ...

Nonlinear THz spectroscopy and simulation of gated graphene

Juan Ramon Mosig, Matthias Gäumann, Michele Tamagnone

We studied the nonlinear optical properties of single layer graphene using high terahertz (THz) fields. With the use of a back gate and cooling down the sample to cryogenic temperatures we are able to spectrally probe the nonlinear THz properties of intrin ...

Phase Corrected H-Plane Horn Antenna in Gap SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

This communication introduces a modified substrate integrated waveguide (SIW), the gap SIW, and deduces an approximate closed-form expression for calculating its effective width, taking into account the fringing and coupling fields around the gap. As an im ...

Experimental verification of optimal frequency range for microwave head imaging

Jean-Philippe Thiran, Juan Ramon Mosig, Michael Mattes, Mina Bjelogrlic, Benjamin Fuchs

This work presents the experimental verification of the power transmission of a radiating field into the human head for Microwave Imaging (MWI) applications. We aim at finding the range of frequencies that optimize the power scattered by any anomalies from ...

Stereolithography-Based Antennas for Satellite Communications in Ka-Band

Juan Ramon Mosig, Tomislav Debogovic, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper illustrates the role of additive manufacturing (AM) as enabling technology to realize high-performance low-cost antennas for Ka-band applications. In addition to the inherent electromagnetic challenges implicit in the conception of such complex ...

High Gain Dual-Band Beam-Steering Transmit Array for Satcom Terminals at Ka-Band

Juan Ramon Mosig, Joana Rita Alves dos Santos Silva

Transmit array design is more challenging for dualband operation than for single band, due to the independent 360 degrees phase wrapping jumps needed at each band when large electrical length compensation is involved. This happens when aiming at large gain ...
