Width-Constrained Multilayer SIW Components Based on Adjoined Folded SIW Transitions
2024 15th German Microwave Conference (GeMiC)Stacked, multilayer substrate integrated waveguide (SIW) components are discussed in this contribution. The superordinate design constraint is the limitation of the lateral dimensions determined by the width of the feed SIWs. This is achieved by using a broadband adjoined SIW-to-folded-SIW transition.

Design of Miniaturized SIW Filter Loaded With Improved CSRR Structures
Electronics, 2023 In recent years, Split-Ring Resonators (SRRs) and Complementary Split-Ring Resonators (CSRRs) have gained significant attention for their unique electromagnetic properties, such as negative permeability and negative permittivity, making them promising ...

Archives of Dermatology, 1949
In 1924 Letterer 1 described a disease characterized by enlargement of the spleen and the liver, associated with anemia and a purpuric eruption. The patient in Letterer's case was an infant 6 months old, who died within four days after admission to the hospital.

Pediatrics, 1971
I have read with interest the article of Dr. D. C. Mauger on Letterer-Siwe's disease complicated with intravascular coagulation (Pediatrics, 47: 435, 1971). I think that the possibility of intravascular coagulation has not been proven conclusively in the absence of measurement of some key factors, especially with the degree of hepatosplenomegaly this ...

SIW fed dielectric resonator antennas (SIW-DRA)
2006 IEEE MTT-S International Microwave Symposium Digest, 2006A novel feeding structure using substrate integrated waveguide (SIW) technique for dielectric resonator antenna (DRA) is presented in this paper. After making studies by simulations for the proposed SIW fed DRAs, the antennas are fabricated using standard PCB process and measured by vector network analyzer (VNA).

Letterer-siwe disease in adults
Cancer, 1989Histiocytosis X (HX) is a rare disorder of histiocytic proliferation characterized by a broad spectrum of clinicopathologic disease. An unusual case of Letterer-Siwe disease (LSD) or subacute disseminated HX in a 71-year-old woman is presented. The patient had a 3-year history of splenomegaly before skin lesions developed.
