Real-world optimization problems often require an external “modeling engine” that computes fitnesses or data that are then input to an objective function. These programs often have much longer ...

Abstract: A recently proposed low-profile frequency-reconfigurable filtering patch antenna is further optimized to achieve a wider frequency tuning range. The design realizes the filtering ...

Abstract: This paper presents a comprehensive analysis of grounded glide-shifted dielectric periodic structures and their application to the design of leaky-wave antennas (LWAs). A modified Rigorous ...
