This study aimed at examining the effects of the feedback types designed based on the regulatory focus theory (i.e., prevention vs. promotion) and reference of comparison (i.e., normative vs. self-referential) on achievement emotions and achievement

In this work, the phase-only synthesis technique is used for beam shaping of a C-Band circularly polarized dual-reflector antenna. The synthesis relies on Particle Swarm Optimization (PSO) by using the element factors of a 100-elements reflectarray.

2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS).
This paper proposes a new unit cell for C-band circularly polarized reconfigurable reflectarray antennas. In order to obtain the desired beam pattern for the antenna, a variable rotation technique which allows a proper phase control in the array and
