Dual-Side Hybrid Embedding Network for Gain Enhancement of Terahertz Amplifiers at Frequencies Near fmax [PDF]
This paper proposes a dual-side hybrid embedding network (DHEN) to mitigate gain degradation in terahertz amplifiers at frequencies near fmax. The proposed approach employs a pre-embedding network for parasitic absorption, followed by Y-embedding for ...

Bent and Branched Microstrip-Line Antennas for Circular Polarization
We analyze three transmission-line antennas using the moment method. Each line antenna comprises a coplanar feed line, loops, and straight segments connecting the loops and feedline. First, we investigate bent and branched line antennas with loops on one

In this paper, a multi-band AMC-backed antenna system characterized with high gain and low-profile is proposed. It is constructed by placing a quad-band coplanar-waveguide (CPW) antenna over an AMC with four zero-phases in the reflection coefficient. The

Enhanced gain in photonic crystal amplifiers [PDF]
We experimentally demonstrate enhanced gain in the slow-light regime of quantum well photonic crystal amplifiers. A strong gain enhancement is observed with the increase of the group refractive index, due to light slow-down. The slow light enhancement is shown in an amplified spontaneous emission study of a 1 QW photonic crystal amplifier.

Design of a Novel Patch Antenna with Enhanced Gain and Side Lobe Reduction [PDF]
The design of an efficient and directive small size antenna, for modern wireless applications, is a major challenge. This paper introduces the design and simulation of new method to enhance the gain and side lobe reduction that improve the performance of

Human-Specific Gain of Function in a Developmental Enhancer [PDF]
Changes in gene regulation are thought to have contributed to the evolution of human development. However, in vivo evidence for uniquely human developmental regulatory function has remained elusive. In transgenic mice, a conserved noncoding sequence ( HACNS1 ) that evolved extremely rapidly ...

Using Permutations to Enhance the Gain of RUQB Technique [PDF]
Quantum key distribution (QKD) techniques usually suffer from a gain problem when comparing the final key to the generated pulses of quantum states. This research permutes the sets that RUQB (Abu-ayyash & Ajlouni, 2008) uses in order to increase the gain.
