Calculation of the Electromagnetic Field of a Rectangular Waveguide With Chiral Medium

Abstract: A rectangular metallic waveguide with a chiral medium is considered in this article. The field distribution inside a rectangular waveguide is investigated. The task is considered in a full vector setting. The mixed finite element method is used to calculate the rectangular waveguide with a chiral medium.

“…The work carried frequency scanning antenna arrays, widely used in airspace surveillance and air traffic control radar systems, in most cases represent a flat equidistant array of linear radiators connected to a multichannel traveling wave power divider based on couplers that are connected in series to the sinusoidal delay line. configurations [23]. It is known that a significant disadvantage of such antennas is a sharp increase in the voltage standing wave ratio at the input of the power divider at a frequency corresponding to the formation of a radiation pattern beam in the direction of the normal to the radiating aperture, as a result of in-phase addition of a large number of even small reflections from periodic inhomogeneities -bends delay lines and taps.…”

“…Delay line period length: (23) where λgn is the wavelength in the delay line at the frequency fn (normal frequency) corresponding to beam formation of the radiation patterns in the direction normal to the antenna array aperture, i.e. at θ = 0°; nλ is the number of wavelengths at the frequency of the normal λgn, forming one period of the delay line.…”

“…The possibility of calculating the characteristics of waveguides with filling described by arbitrary analytical functions makes it possible to pose problems of parametric synthesis aimed at the implementation of devices with given characteristics. In addition, algorithms for calculating inhomogeneously filled circular waveguides can be used to study gradient optical fibers [13][14][15][16][17][18][19][20][21]. This paper proposes a method for calculating the characteristics of wave propagation of a circular shielded waveguide with a radially inhomogeneous dielectric filling, based on a modified Galerkin method as a variant of the spectral method.…”
