Abstract : Coupling of an electromagnetic wave to the lowest order surface magnetostatic wave in a transversely magnetized YIG sample has been observed in S-band. Improved matching into a rutile waveguide has been achieved. Some experimental evidence has been obtained to check the dispersion curve for the surface magnetostatic mode. A new helix has been designed and fabricated, and its loss characteristic has been measured. (Author)
