This work introduces a refined technique for the estimation of films permittivity within the Ka-band using free-space measurement method. Addressing the challenge of wrong solutions in permittivity estimation, our approach incorporates a frequency-de

In this paper, we introduce a 3-D printed lattice core for wide-angle scanning radome operating in the X-band. We explain the fundamental design methodology of the sandwich structure for radome and outline the technique to represent the 3-D printed c

This paper proposes a novel method to predict the radar detection errors in a complex environment by considering slant range and angular error. This method involves analysis of the electromagnetic wave propagation path loss in troposphere using discr

In this paper, we propose a novel algorithm to compute the radiation pattern of a slot array antenna covered with frequency selective surfaces (FSS) based on ray tracing technique. We observe that the proposed algorithm can greatly reduce computation

We study the radar cross section (RCS) property of an aircraft considering the electromagnetic (EM) characteristics of a frequency selective surface (FSS) radome, mounted on the aircraft. Instead of full-wave methods, we utilize high-frequency method

We propose a novel method to calculate the electromagnetic (EM) wave propagation from low-earth orbit satellite (LEO) to a ground station based on the physical optics (PO), ray tracing technique, and geometric optics (GO) considering interpolated atm

In this paper, we numerically study a curved frequency selective surface (FSS) radome, which encloses a waveguide slot array antenna operating at 10GHz, using the ray tracing technique and flat model. The transmission loss (TL) and boresight error (B
