Current models for the microwave polarimetric brightness temperature of the sea surface are reviewed. Results from the physical optics (PO), composite surface, and small slope approximation (SSA) theories are illustrated and compared with an empirical model. All models are shown to predict both first and second harmonic azimuthal variations of sea brightnesses, but the physical effects captured...

This paper presents the shaped reflector antenna by using backscattering technique to achieve the completely broad-beam radiation pattern. The radiation synthesis method for shaped reflector that has to illuminate a predefined circular area are presented by using a variety of discretization of elementary geometrical functions such as, triangular, quadratic, circular, guassian, cosine, squared c...

The manufacturing industry is connecting people and equipment with new digital technologies, enabling a more continuous stream of data to represent processes. With things connected, the interest in connectivity solution that can support communication high reliability availability will increase. fifth generation telecommunication, i.e., 5G has promising features deliver this, but factory environ...

The current near a right-angled comer on a perfectly conducting flat scatterer illuminated by a plane wave is expressed as a sum of three currents. The first is the physical optics (PO) current, which describes the surface effect. The second is the fringe wave (FW) current, which is found from the half-plane solution and accounts for the distortion of the current caused by the edges. The third ...

An efficient physical optics (PO) calculation method is proposed for the electromagnetic (EM) scattering of electrically large targets coated with magnetized plasma characterized by asymmetric tensor dielectric parameters. The outer surface arbitrarily shaped target discretized into triangular elements. According to principle tangent plane approximation and using wave spectrum expansion method,...

radar cross section (rcs) calculation is an important issue of objects stealth and identification. it is necessary to design the rcs software because of the high cost of rcs measurements in practice. in this paper, designing of efficient software using physical optics theorem for radar cross section calculation of the complex perfect electric conductors or complex dielectric objects for high fr...
