On the mode coupling in longitudinally magnetized waveguiding structures

Investigations of Cylindrical Ferrite Coupled Line Junction Using Hybrid Technique

“…In above equations R (1) m (·) and R (2) m (·) denote two linearly independent radial cylindrical functions and depending on the region they are defined as follows:…”

“…According to the coupled-mode model [1] in such section the gyromagnetic coupling occurs resulting in Faraday rotation effect. The wide operation bandwidth and high isolation is obtained, when the Faraday rotation phenomenon is optimal.…”

“…The basic part of ferrite coupled line (FCL) devices is longitudinally magnetized FCL section obtained as a section of two coupled lines placed on ferrite substrate [1][2][3]. According to the coupled-mode model [1] in such section the gyromagnetic coupling occurs resulting in Faraday rotation effect.…”

“…Nonreciprocal devices have been extensively used in modern microwave and millimeter systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In order to obtain the nonreciprocal effects one needs to utilize the ferrite materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] or active elements such as amplifiers [16].…”

“…In order to obtain the nonreciprocal effects one needs to utilize the ferrite materials [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] or active elements such as amplifiers [16]. Recently, the longitudinally magnetized ferrite coupled strip- [2, 4-10, 15, 17, 18] or slotlines [14,19] are being developed and employed to realize integrated nonreciprocal devices.…”
