Radiation Characteristics of the Wood Lens Using Maslov's Method

Abstract

Abstract-The field refracted by a Wood lens is determined analytically and numerically in the focal region by Maslov's method. Results are compared with those obtained by weak focusing approximation and Kirchhoff's diffraction integral. Agreement among them is fairly good when the parameters satisfy the conditions associated to the approximation.

Field Around the Focal Region of a Paraboloidal Reflector Placed in Isotropic Chiral Medium

“…The GO solution is not valid at focal points that is where J = 0, so Maslov's method is used to find the fields around the focal regions of a focusing system as in [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. The equation which is valid around the focal point of a paraboloidal reflector placed in ordinary medium is given as [6] u(r) = k 2π…”

Paraboloidal Reflector in Chiral Medium Supporting Simultaneously Positive Phase Velocity and Negative Phase Velocity

“…Geometrical Optics (GO) and Maslov's method are applied to analyze the field near the caustics of the focusing systems by many authors [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In this work paraboloidal reflector is placed in a medium having strong electromagnetic coupling.…”

High Frequency Expressions for the Field in the Caustic Region of a Cylindrical Reflector Placed in Chiral Medium

“…Focusing systems have been analyzed by many authors [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. A number of research problems have been analyzed using the Maslov's method [10][11][12][13][14][15][16][17][18][19][20][21].…”
